2. Type "msinfo32.exe"

3. Click System Information (App).

4. Check if System Information shows "Can't Collect Information" as shown in the following picture.

Check Windows Management Instrumentation service

1. Open the Windows Services by typing "services" on the Windows Start.

2. Check for the service Windows Management Instrumentation and stop it.

3. Open Notepad (Start -> Run -> Notepad) or another text editor.

4. Add the following text (copy/paste): 

@echo on cd /d c:\temp if not exist %windir%\system32\wbem goto TryInstall cd /d %windir%\system32\wbem net stop winmgmt winmgmt /kill if exist Rep_bak rd Rep_bak /s /q rename Repository Rep_bak for %%i in (*.dll) do RegSvr32 -s %%i for %%i in (*.exe) do call :FixSrv %%i for %%i in (*.mof,*.mfl) do Mofcomp %%i net start winmgmt goto End 
:FixSrv if /I (%1) == (wbemcntl.exe) goto SkipSrv if /I (%1) == (wbemtest.exe) goto SkipSrv if /I (%1) == (mofcomp.exe) goto SkipSrv %1 /Regserver :SkipSrv goto End :TryInstall if not exist wmicore.exe goto End wmicore /s net start winmgmt :End

5. Save the document with the name "WBEM_Fix.bat" in the folder C:\Autodesk (the location can be changed but avoid the Desktop or user folders).

6. Right-click the BAT file and select Run as administrator.

7. A Command prompt will appear and will perform several steps. Let the process run until it closes automatically.
