.NET Forum / .NET Framework / CLR / November 2005Word and Excel loads version 1.1 of the CLR instead of 2.0 (Beta 2 -> RTM issue)
We are in the process of migrating from Beta 2 to the RTM version of Visual Studio 2005 and the .NET Framework. After the RTM version has been installed, Word and Excel no longer load the 2.0 framework for our C# addin, but instead version 1.1. For some unknown reason PowerPoint still loads 2.0 correctly?! I've tested on machines with VS2005 RTM and on machines with the runtime only. The problem occurs for Office 2003 running on Windows XP SP2. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/html/g ngrfrequiredruntime.asp mentions a requiredRuntime element which can specify that excel or word should load v2.0 of the CLR, but adding the excel.exe.config and word.exe.config to the office folder seems to be a quick-fix until some overwrites these files. Hi Jim, Thanks for your post. Based on my understanding, your Word/Excel addin does not load the lastest CLR, while it still load .Net 1.1. Based on our test on Windows XP SP2, the Office Addin should load the lastest version of CLR. So this issue maybe your machine-specific. I suggest you try this issue on other machines. Also, if you can not go with the config file workaround, I think you may try to clearly remove the .Net Framework and re-install a RTM .Net Framework. Then this problem should go away. To clearly remove both .Net Framework 1.1, I suggest you remove it manually following the KB below: "How to troubleshoot Microsoft .NET Framework 1.1 installation issues" http://support.microsoft.com/?id=824643 To remove .Net Framework2.0, just go to Add/Remove in Control panel and remove it. Hope it helps Best regards, Jeffrey Tan Microsoft Online Partner Support  SignatureGet Secure! - www.microsoft.com/security This posting is provided "as is" with no warranties and confers no rights. I appears that it works correctly for users that are not local administrators on the current machine. For these users, the .NET Runtime adds the following to the Application Event Log when Word, Excel or PowerPoint starts: "The following information is part of the event: Unable to open shim database version registry key - v2.0.50727.00000." This event log message does not appear for users that are local administrators. Reinstalling the .NET framework has no effect on the problem. I hope this information can help resolve the issue.

Update: I attached RegMon to Word during startup, and it used the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\AppPatch\v2.0.50727.00000\winword.exe Which contains the following values: ------------ [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\AppPatch\v2.0.50727.00000\winword.exe] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\AppPatch\v2.0.50727.00000\winword.exe\{2CCAA9FE-6884-4AF2-99DD-5217B94115DF}] "Minimum File Version Number"="11.0.0.0" "Maximum File Version Number"="11.0.9999.9999" "Target Version"="v1.1.4322" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\AppPatch\v2.0.50727.00000\winword.exe\{2CCAA9FE-6884-4AF2-99DD-5217B94115DF}\Registry Keys] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\AppPatch\v2.0.50727.00000\winword.exe\{2CCAA9FE-6884-4AF2-99DD-5217B94115DF}\Registry Keys\{2CCAA9FE-6884-4AF2-99DD-5217B94115DF}] "Key Presence"=dword:00000000 "Key Name"="HKEY_CLASSES_ROOT\\Interface\\{000C0601-0000-0000-C000-000000000046}" ------------ If I rename the winword.exe registry key to winword2.exe for example, word loads v2.0 of the CLR as expected, and the addin loads successfully. For some reason, powerpoint.exe has not been added to the AppPatch registry key, which explains why PowerPoint works. My immediate impulse is to delete the registry keys for Word an PowerPoint, but I've found no documentation about the registry key, so I not sure it's the right solution. > I appears that it works correctly for users that are not local > administrators on the current machine.

I do not think it is this registry key that caused your strange problem. Because on my test machine, it has the same registry structure as you posted. However, I do not know why after renaming this registry key, your word will correctly load .Net2.0 CLR now. Anyway, because this registry resides in my work well machine, I do not suggest you to delete this registry key, because this may cause some serious issue.

I'm almost 100% sure it does cause the problem - let me explain: RegMon shows that when word runs for a non-administrator, Word gets an Access Denied result when it attempts to open the AppPach registry key: WINWORD.EXE:2324 OpenKey HKLM\Software\Microsoft\.NETFramework\Policy\AppPatch\v2.0.50727.00000 ACCESS DENIED Access: 0xF003F TESTLAB\nonadminuser For users with local administrator rights word successfully reads the key and loads the specified 1.1 target version (which is wrong in our case). So the registry key does determine the application compatibility setting for the CLR version. I've tried this across multiple test machine - admin users get v1.1 of the CLR in Word and Excel, while non-admin users on the same machine get v2.0 since the AppPatch key is not successfully read by word and excel. For both types of users, PowerPoint loads v2.0, since there is no powerpoint.exe listed under the AppPatch registry key. I believe that the purpose of the AppPatch registry key is to prevent v2.0 braking changes to affect word and excel addins running v1.1 of the framework. Hi Jim, Thanks for your feedback. This is really a strange issue. I have consulted our product team for this issue, and based on the feedback, this issue can be fixed by installing the update below: http://www.microsoft.com/downloads/details.aspx?FamilyId=1B0BFB35-C252-43CC- 8A2A-6A64D6AC4670&displaylang=en So I suggest you install this update and check if it resolves your problem. Thanks Best regards, Jeffrey Tan Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "as is" with no warranties and confers no rights.
