Clr20r3 Error Windows 2012 R2

Did you try to run the application under debugger? (Use for example windbg, collect a dump and debug it) Another option is to set the machine to start debugger whenever the process starts (gflags in Windows SDK) or automatically collect crash dumps when process crashes (AeDebug, etc.). I developed an applicatin using Visual Studio.Net 2008 Team System with Infragistics Net Advantage Tools 2010.3 and made a Setup Exe file for my application and installed on client machines where.

I downloaded Windows Server 2012 R2 from microsoft.com as a .vhd file and am using virtualBox to run it. After downloading it, I changed the execution policy to remoteSigned, then changed the name of the computer from the standard WIN-gibberish. I restarted the computer, but on boot, server manager came up with the error:

Server Manager cannot run because of an error in a user settings file. Click OK to restore default settings and continue, or click Cancel to exit. The configuration section 'connectionStrings' has an unexpected declaration.

I clicked OK and then received a notification that the Server Manager has stopped working, giving me the options of checking online for a solution, or closing the program. When I expanded View problem details the following was displayed:

I researched it a bit(actually a lot) and didn't find a clear resolution to this. The only resolution was on a Microsoft website where they said to update the framework. On that site OP never responded, and the question answerer marked their answer as correct.

So far I've tried:

  • Installing all Windows Updates

    Winnie the pooh online games. Mickey's Fun Songs 1994 Preview6. Winnie the Pooh Playtime Opening Logo9. Disney's Sing-Along Songs 1995 Preview7. 'Feature Program'8.

  • Verifying .NET is up to date

  • Running DISM.exe /Online /Cleanup-image /Restorehealth in the console, per https://support.microsoft.com/en-us/kb/947821

  • Renaming the computer to what it was previously

  • Changing the execution policy to default

  • Running WMIDiag.exe which reported the following error: 0x8004100E - (WBEM_E_INVALID_NAMESPACE) Namespace specified cannot be found

Edit:

  • Found a folder in C:UsersAdministratorAppDataRoamingMicrosoftWindowsServerManager that contained a file, ServerList.Xml, that was referencing the old name of the computer. Renaming this file does not resolve the issue.

I ended up re-downloading the .vhd file which isn't really a solution but does resolve the issue. After I create a copy of the .vhd, I'll try to duplicate the issue.Does anyone have suggestions to what I(or anyone else) that runs across this issue should try?

There is a user setting file at C:UsersYourUserNameAppDataLocalMicrosoft_CorporationServerManager.exe_StrongName_m3xk0k0ucj0oj3ai2hibnhnv4xobnimj10.0.0.0user.config. This file will be updated when user made any setting change on UI, and sometime this file can get corrupted because of crash or turn-off.

Try manually deleting the file and restarting Server Manager.

I had this issue after upgrading from 2008 R2 to 2012 R2.

Installing the latest version of .NET Framework (4.7) from Microsoft's website fixed the issue.

I was having the same issue on Server 2012 R2 with Essentials role enabled.

I attempted deleting the config file as mentioned above and it did not yield the desired result.

I have seen on other sites where there is an issue with in graphics adapter. I checked the adapter driver and noted that it had been updated. I rolled backed the adapter driver and now the server manager is working as it should.

Its the issue with the graphics driver. uninstall it and restart the server. server manager will be working fine. its worked for me.
