Hi&nbsp;Russ,&nbsp;  
  
  
  
For&nbsp;your&nbsp;exception,&nbsp;it&nbsp;looks&nbsp;that’s&nbsp;because&nbsp;missed&nbsp;the&nbsp;CAD&nbsp;support&nbsp;dll&nbsp;package.&nbsp;  
  
  
  
Please&nbsp;view&nbsp;this&nbsp;wiki&nbsp;page:&nbsp;  
  
[wiki.thinkgeo.com/wiki/Map\_Suite\_Services\_Edition\_Deployment\_Guide](http://wiki.thinkgeo.com/wiki/Map_Suite_Services_Edition_Deployment_Guide)&nbsp;  
  
  
  
And&nbsp;you&nbsp;can&nbsp;download&nbsp;the&nbsp;package&nbsp;here:&nbsp;  
  
[wiki.thinkgeo.com/wiki/File:MapSuiteCadX642014-07-28.zip](http://wiki.thinkgeo.com/wiki/File:MapSuiteCadX642014-07-28.zip)

Wish&nbsp;that’s&nbsp;helpful.&nbsp;  
  
  
  
For&nbsp;your&nbsp;mentioned&nbsp;exception&nbsp;thrown&nbsp;by&nbsp;this&nbsp;code:&nbsp;  
  
MapShape&nbsp;mapShape1&nbsp;=&nbsp;new&nbsp;MapShape(new&nbsp;Feature(-104,&nbsp;42));&nbsp;  
  
  
  
I&nbsp;think&nbsp;we&nbsp;need&nbsp;more&nbsp;code&nbsp;about&nbsp;how&nbsp;class&nbsp;MapShape&nbsp;and&nbsp;we&nbsp;can&nbsp;know&nbsp;what&nbsp;happen&nbsp;in&nbsp;it.&nbsp;

As&nbsp;I&nbsp;said,&nbsp;MapShape&nbsp;is&nbsp;in&nbsp;YOUR&nbsp;code,&nbsp;in&nbsp;the&nbsp;sample&nbsp;I&nbsp;referenced.&nbsp;And&nbsp;the&nbsp;recursion&nbsp;is&nbsp;inside&nbsp;your&nbsp;component&nbsp;code&nbsp;beginning&nbsp;with&nbsp;the&nbsp;“new&nbsp;Feature(-104,&nbsp;42)”&nbsp;ctor&nbsp;argument.&nbsp;&nbsp;So&nbsp;I&nbsp;would&nbsp;think&nbsp;you&nbsp;would&nbsp;know&nbsp;all&nbsp;about&nbsp;that&nbsp;code.&nbsp;

&nbsp;Thanks&nbsp;for&nbsp;let&nbsp;us&nbsp;know&nbsp;the&nbsp;problem,&nbsp;I&nbsp;reproduce&nbsp;your&nbsp;issue&nbsp;and&nbsp;found&nbsp;that&nbsp;caused&nbsp;by&nbsp;the&nbsp;MapSuiteCore.dll&nbsp;reference&nbsp;haven’t&nbsp;been&nbsp;updated&nbsp;to&nbsp;the&nbsp;latest&nbsp;in&nbsp;the&nbsp;sample.&nbsp;  
&nbsp;&nbsp;  
&nbsp;I&nbsp;tested&nbsp;with&nbsp;8.0.0.50&nbsp;today&nbsp;and&nbsp;it&nbsp;works&nbsp;well.&nbsp;  
&nbsp;&nbsp;  
&nbsp;What&nbsp;you&nbsp;want&nbsp;to&nbsp;do&nbsp;is:&nbsp;  
&nbsp;&nbsp;  
&nbsp;1.&nbsp;Setup&nbsp;Unmanaged&nbsp;Dependencies,&nbsp;that&nbsp;will&nbsp;install&nbsp;CAD&nbsp;support&nbsp;dlls&nbsp;to&nbsp;system&nbsp;folder.&nbsp;  
&nbsp;2.&nbsp;Download&nbsp;our&nbsp;latest&nbsp;dll&nbsp;package,&nbsp;remove&nbsp;original&nbsp;reference&nbsp;and&nbsp;reference&nbsp;the&nbsp;new&nbsp;one.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Wish&nbsp;that’s&nbsp;helpful.&nbsp;

No&nbsp;you&nbsp;have&nbsp;not&nbsp;reproduced&nbsp;my&nbsp;issue.&nbsp;&nbsp;&nbsp;  
  
  
  
1)&nbsp;The&nbsp;MapSuiteCore.dll&nbsp;reference&nbsp;update&nbsp;is&nbsp;a&nbsp;compile&nbsp;error&nbsp;due&nbsp;to&nbsp;reference&nbsp;path.&nbsp;Both&nbsp;problems&nbsp;I&nbsp;reported&nbsp;are&nbsp;runtime&nbsp;errors,&nbsp;so&nbsp;clearly&nbsp;I&nbsp;got&nbsp;past&nbsp;the&nbsp;compile.&nbsp;  
  
  
  
2)&nbsp;I’ve&nbsp;already&nbsp;stated&nbsp;that&nbsp;I&nbsp;can&nbsp;find&nbsp;no&nbsp;information&nbsp;on&nbsp;your&nbsp;site&nbsp;to&nbsp;download&nbsp;the&nbsp;unmanaged&nbsp;assemblies&nbsp;installer.&nbsp;&nbsp;Searching&nbsp;your&nbsp;entire&nbsp;site&nbsp;(from&nbsp;top&nbsp;of&nbsp;main&nbsp;page)&nbsp;last&nbsp;week&nbsp;failed&nbsp;to&nbsp;produce.&nbsp;&nbsp;I&nbsp;just&nbsp;tried&nbsp;again&nbsp;and&nbsp;get&nbsp;a&nbsp;403&nbsp;this&nbsp;time.&nbsp;&nbsp;I&nbsp;did&nbsp;see&nbsp;comments&nbsp;regarding&nbsp;it&nbsp;(sometimes)&nbsp;being&nbsp;part&nbsp;of&nbsp;the&nbsp;daily&nbsp;build&nbsp;images,&nbsp;but&nbsp;my&nbsp;requirement&nbsp;is&nbsp;to&nbsp;use&nbsp;the&nbsp;release,&nbsp;not&nbsp;daily&nbsp;builds.  
  
&nbsp;&nbsp;  
  
So,&nbsp;assuming&nbsp;you&nbsp;ran&nbsp;the&nbsp;actual&nbsp;scenarios&nbsp;I&nbsp;posted&nbsp;and&nbsp;didn’t&nbsp;get&nbsp;the&nbsp;runtime&nbsp;errors&nbsp;(one&nbsp;a&nbsp;fail&nbsp;to&nbsp;load,&nbsp;the&nbsp;other&nbsp;an&nbsp;infinite&nbsp;recursion),&nbsp;it&nbsp;seems&nbsp;these&nbsp;unmanaged&nbsp;dependencies&nbsp;provide&nbsp;the&nbsp;answer.&nbsp;&nbsp;Now,&nbsp;can&nbsp;you&nbsp;answer&nbsp;where&nbsp;I&nbsp;might&nbsp;find&nbsp;them?&nbsp;&nbsp;Hopefully&nbsp;without&nbsp;waiting&nbsp;until&nbsp;tomorrow&nbsp;morning…

Ok,&nbsp;I&nbsp;decided&nbsp;to&nbsp;start&nbsp;looking&nbsp;again,&nbsp;and&nbsp;found&nbsp;the&nbsp;unmanaged&nbsp;msi.&nbsp;  
  
  
  
“C:\Program&nbsp;Files&nbsp;(x86)\ThinkGeo\Map&nbsp;Suite&nbsp;8.0\Map&nbsp;Suite&nbsp;Desktop\Daily&nbsp;Full&nbsp;Development&nbsp;8.0.154.0\Map&nbsp;Suite&nbsp;Unmanaged&nbsp;Dependencies&nbsp;8.0.122.0.msi”&nbsp;  
  
  
  
I’m&nbsp;surprised&nbsp;I&nbsp;missed&nbsp;it,&nbsp;but&nbsp;still&nbsp;can’t&nbsp;believe&nbsp;that&nbsp;your&nbsp;site&nbsp;continually&nbsp;refers&nbsp;to&nbsp;it&nbsp;without&nbsp;any&nbsp;indication&nbsp;of&nbsp;where&nbsp;to&nbsp;find&nbsp;it&nbsp;(that&nbsp;I&nbsp;found).&nbsp;&nbsp;I&nbsp;would&nbsp;think&nbsp;it&nbsp;would&nbsp;be&nbsp;very&nbsp;clear.&nbsp;  
  
  
  
In&nbsp;any&nbsp;case,&nbsp;this&nbsp;did&nbsp;not&nbsp;fix&nbsp;my&nbsp;problem.&nbsp;  
  
  
  
DisplayCadFile,&nbsp;rebuilt&nbsp;after&nbsp;running&nbsp;the&nbsp;unamanaged&nbsp;msi,&nbsp;and&nbsp;referencing&nbsp;the&nbsp;installed&nbsp;8.0&nbsp;MapSuiteCore&nbsp;dll&nbsp;(see&nbsp;below),&nbsp;I&nbsp;still&nbsp;get&nbsp;the&nbsp;same&nbsp;error&nbsp;at&nbsp;the&nbsp;same&nbsp;line.&nbsp;  
  
  
  
mapEngine&nbsp;=&nbsp;new&nbsp;MapEngine();&nbsp;  
  
  
  
Referencing:&nbsp;C:\Program&nbsp;Files&nbsp;(x86)\ThinkGeo\Map&nbsp;Suite&nbsp;8.0\Map&nbsp;Suite&nbsp;Services\Current&nbsp;Version\Managed&nbsp;Assemblies\MapSuiteCore.dll&nbsp;  
  
  
  
Likewise,&nbsp;after&nbsp;running&nbsp;the&nbsp;unmanaged&nbsp;msi,&nbsp;I&nbsp;still&nbsp;get&nbsp;the&nbsp;stack&nbsp;overflow&nbsp;in&nbsp;the&nbsp;Exploring&nbsp;Layers&nbsp;sample.&nbsp;  
  
  
  
So&nbsp;in&nbsp;short,&nbsp;the&nbsp;unmanaged&nbsp;dependencies&nbsp;msi&nbsp;appears&nbsp;not&nbsp;to&nbsp;correct&nbsp;the&nbsp;problem.&nbsp;  
  
  
  
For&nbsp;reference&nbsp;I&nbsp;am&nbsp;is&nbsp;running  
  
  
  
VS&nbsp;2013&nbsp;Update&nbsp;2  
  
Win&nbsp;8.1  
  
Your&nbsp;“8.0.0.0”&nbsp;product.

I’ll&nbsp;repeat&nbsp;again.&nbsp;&nbsp;I&nbsp;am&nbsp;confident&nbsp;I&nbsp;can&nbsp;manage&nbsp;our&nbsp;data&nbsp;once&nbsp;things&nbsp;work.&nbsp;&nbsp;The&nbsp;problem&nbsp;is&nbsp;that&nbsp;YOUR&nbsp;samples&nbsp;don’t&nbsp;work&nbsp;for&nbsp;me.&nbsp;&nbsp;They&nbsp;crash&nbsp;inside&nbsp;the&nbsp;core&nbsp;library&nbsp;code.&nbsp;&nbsp;If&nbsp;the&nbsp;samples&nbsp;relating&nbsp;to&nbsp;features&nbsp;we&nbsp;need&nbsp;don’t&nbsp;work,&nbsp;there&nbsp;is&nbsp;no&nbsp;point&nbsp;in&nbsp;trying&nbsp;to&nbsp;get&nbsp;our&nbsp;more&nbsp;complex&nbsp;real&nbsp;data&nbsp;to&nbsp;work.&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;So&nbsp;please&nbsp;do&nbsp;as&nbsp;I&nbsp;ask.&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;Take&nbsp;a&nbsp;clean&nbsp;system&nbsp;and&nbsp;install&nbsp;your&nbsp;8.0&nbsp;release&nbsp;MSI.&nbsp;&nbsp;If&nbsp;you&nbsp;use&nbsp;Win&nbsp;8.1,&nbsp;VS2013&nbsp;(update&nbsp;2),&nbsp;your&nbsp;8.0&nbsp;release&nbsp;and&nbsp;the&nbsp;samples&nbsp;indicated,&nbsp;I&nbsp;am&nbsp;confident&nbsp;you&nbsp;can&nbsp;reproduce&nbsp;EXACTLY&nbsp;what&nbsp;I’m&nbsp;describing&nbsp;on&nbsp;YOUR&nbsp;system&nbsp;without&nbsp;any&nbsp;further&nbsp;information&nbsp;from&nbsp;ME.&nbsp;&nbsp;This&nbsp;is&nbsp;your&nbsp;samples&nbsp;and&nbsp;your&nbsp;libraries&nbsp;that&nbsp;are&nbsp;crashing.&nbsp;&nbsp;Not&nbsp;one&nbsp;line&nbsp;of&nbsp;my&nbsp;code&nbsp;involved.&nbsp;&nbsp;The&nbsp;only&nbsp;thing&nbsp;I&nbsp;did&nbsp;to&nbsp;your&nbsp;samples&nbsp;was&nbsp;update&nbsp;them&nbsp;to&nbsp;point&nbsp;to&nbsp;the&nbsp;current&nbsp;release&nbsp;bins&nbsp;in&nbsp;the&nbsp;install&nbsp;folder.&nbsp;

Ok,&nbsp;looks&nbsp;like&nbsp;this&nbsp;is&nbsp;resolved&nbsp;via&nbsp;an&nbsp;online&nbsp;assist.&nbsp;&nbsp;The&nbsp;problem&nbsp;appears&nbsp;to&nbsp;have&nbsp;resulted&nbsp;from&nbsp;multiple&nbsp;sources.&nbsp;&nbsp;One&nbsp;may&nbsp;have&nbsp;been&nbsp;related&nbsp;to&nbsp;the&nbsp;version&nbsp;that&nbsp;was&nbsp;available&nbsp;before&nbsp;a&nbsp;refresh&nbsp;that&nbsp;apparently&nbsp;occurred&nbsp;yesterday.&nbsp;&nbsp;It&nbsp;appears&nbsp;that&nbsp;the&nbsp;previous&nbsp;version&nbsp;may&nbsp;have&nbsp;had&nbsp;an&nbsp;issue,&nbsp;that&nbsp;appears&nbsp;also&nbsp;in&nbsp;the&nbsp;new&nbsp;version&nbsp;we&nbsp;installed&nbsp;(while&nbsp;using&nbsp;shared&nbsp;desktop)&nbsp;today.&nbsp;&nbsp;The&nbsp;verified&nbsp;problem&nbsp;with&nbsp;the&nbsp;current&nbsp;install&nbsp;(and&nbsp;apparently&nbsp;previous)&nbsp;was&nbsp;missing&nbsp;CAD&nbsp;support&nbsp;that&nbsp;should&nbsp;have&nbsp;been&nbsp;part&nbsp;of&nbsp;the&nbsp;standard&nbsp;registered&nbsp;install.&nbsp;&nbsp;We&nbsp;had&nbsp;to&nbsp;add&nbsp;those&nbsp;manually&nbsp;to&nbsp;C:\Windows\SysWOW64\Map&nbsp;Suite&nbsp;8.0\CadX64&nbsp;(not&nbsp;SystemRoot&nbsp;as&nbsp;specified&nbsp;in&nbsp;guide).&nbsp;  
&nbsp;&nbsp;  
&nbsp;Another&nbsp;source&nbsp;of&nbsp;problem&nbsp;appears&nbsp;to&nbsp;have&nbsp;crept&nbsp;in&nbsp;while&nbsp;trying&nbsp;to&nbsp;fix&nbsp;the&nbsp;CAD&nbsp;support.&nbsp;&nbsp;At&nbsp;some&nbsp;point&nbsp;I&nbsp;managed&nbsp;to&nbsp;install&nbsp;the&nbsp;“evaluation&nbsp;version”,&nbsp;which&nbsp;updated&nbsp;my&nbsp;“current”&nbsp;bins&nbsp;folder&nbsp;under&nbsp;Program&nbsp;Files&nbsp;(x86).&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;So&nbsp;the&nbsp;resolution&nbsp;was&nbsp;to&nbsp;remove&nbsp;all&nbsp;traces&nbsp;of&nbsp;the&nbsp;Map&nbsp;Suite&nbsp;from&nbsp;my&nbsp;test&nbsp;VM.&nbsp;&nbsp;That&nbsp;included&nbsp;uninstall&nbsp;followed&nbsp;by&nbsp;manual&nbsp;removal&nbsp;of&nbsp;all&nbsp;traces&nbsp;from&nbsp;within&nbsp;both&nbsp;SysWow64&nbsp;and&nbsp;Program&nbsp;Files&nbsp;(x86).&nbsp;&nbsp;We&nbsp;then&nbsp;installed&nbsp;the&nbsp;latest&nbsp;product&nbsp;center,&nbsp;logged&nbsp;in&nbsp;with&nbsp;registered&nbsp;account,&nbsp;and&nbsp;then&nbsp;installed&nbsp;the&nbsp;“Full&nbsp;Production”&nbsp;download.&nbsp;&nbsp;Finally&nbsp;we&nbsp;manually&nbsp;added&nbsp;the&nbsp;CAD&nbsp;support&nbsp;to&nbsp;SysWow64,&nbsp;and&nbsp;both&nbsp;samples&nbsp;I&nbsp;reported&nbsp;are&nbsp;now&nbsp;working&nbsp;correctly.&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;  
&nbsp;I’m&nbsp;now&nbsp;awaiting&nbsp;a&nbsp;fully&nbsp;supported&nbsp;install&nbsp;update&nbsp;that&nbsp;works&nbsp;correctly&nbsp;without&nbsp;the&nbsp;manual&nbsp;steps&nbsp;required.&nbsp;&nbsp;This&nbsp;is&nbsp;required&nbsp;to&nbsp;accept&nbsp;the&nbsp;update&nbsp;to&nbsp;Map&nbsp;Suite&nbsp;8.0&nbsp;internally.&nbsp;&nbsp;Hopefully&nbsp;they&nbsp;will&nbsp;be&nbsp;able&nbsp;to&nbsp;provide&nbsp;this&nbsp;official&nbsp;“production”&nbsp;update&nbsp;release&nbsp;soon.&nbsp;&nbsp;But&nbsp;until&nbsp;then,&nbsp;at&nbsp;least&nbsp;I&nbsp;can&nbsp;continue&nbsp;with&nbsp;my&nbsp;project…

Hi&nbsp;Russ,  
  
  
  
We&nbsp;are&nbsp;sorry&nbsp;Don&Johnny&nbsp;might&nbsp;not&nbsp;catch&nbsp;the&nbsp;correct&nbsp;point&nbsp;on&nbsp;your&nbsp;question.&nbsp;I&nbsp;reviewed&nbsp;your&nbsp;issues&nbsp;and&nbsp;please&nbsp;let&nbsp;me&nbsp;explain&nbsp;something&nbsp;on&nbsp;unmanaged&nbsp;dependencies:  
  
  
  
In&nbsp;order&nbsp;to&nbsp;support&nbsp;some&nbsp;special&nbsp;features&nbsp;in&nbsp;map&nbsp;suite,&nbsp;like&nbsp;CAD,&nbsp;Ecw,&nbsp;Jp2,&nbsp;FGDB,etc,&nbsp;we&nbsp;always&nbsp;need&nbsp;to&nbsp;refer&nbsp;to&nbsp;the&nbsp;third-party&nbsp;dependencies&nbsp;dlls&nbsp;and&nbsp;those&nbsp;dlls&nbsp;are&nbsp;included&nbsp;in&nbsp;an&nbsp;installer&nbsp;named&nbsp;&nbsp;"Unmanaged&nbsp;Dependencies.msi".&nbsp;This&nbsp;installer&nbsp;is&nbsp;responsible&nbsp;to&nbsp;unzip&nbsp;those&nbsp;dlls&nbsp;under&nbsp;"systemRoot"&nbsp;automatically.&nbsp;The&nbsp;systemRoot&nbsp;folder&nbsp;means&nbsp;the&nbsp;folder&nbsp;"C:\Windows\System32"&nbsp;or&nbsp;"C:\Windows\sysWOW64":  
  
  
  
Case1:&nbsp;&nbsp;app&nbsp;win32&nbsp;version&nbsp;on&nbsp;32bit&nbsp;system&nbsp;=\>&nbsp;system32  
  
Case2:&nbsp;&nbsp;app&nbsp;win32&nbsp;version&nbsp;on&nbsp;64bit&nbsp;system&nbsp;=\>&nbsp;sysWOW64  
  
Case3:&nbsp;&nbsp;app&nbsp;win64&nbsp;version&nbsp;on&nbsp;64bit&nbsp;system&nbsp;=\>&nbsp;system32  
  
  
  
So,&nbsp;after&nbsp;we&nbsp;install&nbsp;the&nbsp;Unmanaged&nbsp;Dependencies.msi,&nbsp;we&nbsp;should&nbsp;see&nbsp;the&nbsp;below&nbsp;dll&nbsp;structure.&nbsp;  
  
As&nbsp;for&nbsp;the&nbsp;Unmanaged&nbsp;Dependencies.msi&nbsp;installer&nbsp;you&nbsp;are&nbsp;looking&nbsp;for,&nbsp;I&nbsp;have&nbsp;to&nbsp;say&nbsp;sorry&nbsp;again&nbsp;we&nbsp;did&nbsp;a&nbsp;strategy&nbsp;change&nbsp;that&nbsp;customer&nbsp;can’t&nbsp;download&nbsp;it&nbsp;directly&nbsp;via&nbsp;product&nbsp;center&nbsp;or&nbsp;customer&nbsp;portal&nbsp;since&nbsp;8.0.&nbsp;But&nbsp;I&nbsp;agree&nbsp;to&nbsp;public&nbsp;it&nbsp;somewhere&nbsp;like&nbsp;before&nbsp;so&nbsp;that&nbsp;you&nbsp;can&nbsp;feel&nbsp;free&nbsp;to&nbsp;download&nbsp;it&nbsp;and&nbsp;I&nbsp;will&nbsp;let&nbsp;my&nbsp;leader&nbsp;knows&nbsp;if&nbsp;we&nbsp;have&nbsp;a&nbsp;solution&nbsp;on&nbsp;this&nbsp;stuff.&nbsp;For&nbsp;temporary,&nbsp;I&nbsp;shared&nbsp;it&nbsp;and&nbsp;please&nbsp;download&nbsp;it&nbsp;from&nbsp;[ap.thinkgeo.com:5001/fbsharing/3Pvu5UQT](https://ap.thinkgeo.com:5001/fbsharing/3Pvu5UQT)

Thanks&nbsp;for&nbsp;the&nbsp;help.&nbsp;  
  
  
  
I&nbsp;think&nbsp;the&nbsp;root&nbsp;of&nbsp;that&nbsp;“unmanaged&nbsp;dependencies”&nbsp;question&nbsp;was&nbsp;that&nbsp;the&nbsp;installer&nbsp;of&nbsp;the&nbsp;moment&nbsp;was&nbsp;not&nbsp;correctly&nbsp;installing&nbsp;the&nbsp;CAD&nbsp;files.&nbsp;&nbsp;The&nbsp;resulting&nbsp;error&nbsp;had&nbsp;me&nbsp;looking&nbsp;for&nbsp;answers,&nbsp;running&nbsp;across&nbsp;the&nbsp;references&nbsp;to&nbsp;the&nbsp;“unmanaged&nbsp;dependencies&nbsp;installer”,&nbsp;and&nbsp;then&nbsp;not&nbsp;being&nbsp;able&nbsp;to&nbsp;find&nbsp;where&nbsp;to&nbsp;get&nbsp;it.&nbsp;  
  
  
  
Also,&nbsp;just&nbsp;for&nbsp;reference,&nbsp;“SystemRoot”&nbsp;has&nbsp;a&nbsp;very&nbsp;specific&nbsp;meaning&nbsp;for&nbsp;most&nbsp;Windows&nbsp;devs,&nbsp;and&nbsp;it’s&nbsp;been&nbsp;unchanged&nbsp;since&nbsp;early&nbsp;versions&nbsp;of&nbsp;Windows.&nbsp;&nbsp;It’s&nbsp;a&nbsp;standard&nbsp;environment&nbsp;variable,&nbsp;which&nbsp;is&nbsp;by&nbsp;default&nbsp;configured&nbsp;as&nbsp;“SystemRoot=C:\WINDOWS”.&nbsp;&nbsp;I&nbsp;would&nbsp;say&nbsp;it&nbsp;is&nbsp;a&nbsp;mistake&nbsp;for&nbsp;ThinkGeo&nbsp;to&nbsp;redefine&nbsp;this&nbsp;since&nbsp;it&nbsp;can&nbsp;easily&nbsp;cause&nbsp;the&nbsp;confusion&nbsp;I&nbsp;experienced.&nbsp;&nbsp;And&nbsp;I&nbsp;will&nbsp;also&nbsp;say&nbsp;that&nbsp;I&nbsp;never&nbsp;found&nbsp;where&nbsp;they&nbsp;define&nbsp;it&nbsp;at&nbsp;all,&nbsp;so&nbsp;was&nbsp;left&nbsp;only&nbsp;with&nbsp;my&nbsp;experience&nbsp;based&nbsp;interpretation.

I&nbsp;am&nbsp;also&nbsp;curious&nbsp;why&nbsp;the&nbsp;CAD&nbsp;dlls&nbsp;are&nbsp;not&nbsp;there&nbsp;after&nbsp;the&nbsp;installer&nbsp;is&nbsp;installed.&nbsp;But&nbsp;based&nbsp;on&nbsp;our&nbsp;test,&nbsp;the&nbsp;unmanaged&nbsp;dependencies&nbsp;installer&nbsp;is&nbsp;correct.  
  
Another&nbsp;thing&nbsp;is&nbsp;the&nbsp;unmanaged&nbsp;dependencies&nbsp;installer&nbsp;is&nbsp;integrated&nbsp;into&nbsp;dll&nbsp;packages&nbsp;now&nbsp;and&nbsp;we&nbsp;can&nbsp;find&nbsp;it&nbsp;within&nbsp;the&nbsp;dlls&nbsp;packages.  
  
  
  
As&nbsp;for&nbsp;the&nbsp;"SystemRoot",&nbsp;Oh,&nbsp;I&nbsp;think&nbsp;you&nbsp;might&nbsp;be&nbsp;right&nbsp;after&nbsp;some&nbsp;searching.&nbsp;I&nbsp;will&nbsp;let&nbsp;my&nbsp;leader&nbsp;to&nbsp;know&nbsp;if&nbsp;we&nbsp;can&nbsp;add&nbsp;more&nbsp;descriptions&nbsp;on&nbsp;the&nbsp;dependencies&nbsp;guide&nbsp;page.&nbsp;  
  
  
  
Any&nbsp;questions,&nbsp;please&nbsp;feel&nbsp;free&nbsp;to&nbsp;let&nbsp;us&nbsp;know.  
  
Thanks,  
  
Troy
