CqvSvc.exe System.Management.ManagementException 'Invalid class' RRS feed

  • General discussion

  • Just wanted to let you know that I'm getting this message in the application event log every minute. Disabled the service for now. There's something wrong with this CqvSvc.exe.

  • Hi,
    According to this thread the CqvSvc.exe is the Console QuickView Monitor Service (part of the new Media Center functionality).
    Looks like a problem with the installation of PP3?

    No home server like Home Server

  • Hi,
    I did battle a little bit longer with that stuff now after getting the event log flooded with messages from cqvSvc.exe "Initialization failed". Also the health.xml was no longer upgraded.
    Since this happened after an unexpected power outage while powering up and there was also an error with accessing the Repository folder I decided to stop wmimgmt service, delete the folder and reboot the server.
    This fixed another behavior (my Scaleo Home Server could not start the Intel Hardware Monitor any more), but the warning generated by cqvSvc.exe in event log changed to Invalid class. Since I am not a programmer and using Dependency Walker on the exe file did not reveal anything for me, I attempted to uninstall and reinstall the service by the commands:
    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\installutil /u "C:\Program Files\Windows Home Server\cqvsvc.exe"
    which should successfully remove the service
    C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\installutil /u "C:\Program Files\Windows Home Server\cqvsvc.exe"
    for installing the service again.
    Rebooted - and still the same warning.
    So I decided to run another round in the WMI struggle by executing the following batch (which I had still from another situation, in which I needed to repair WMI on a production server) - put the lines into a file and save it with extension .cmd before executing it on your server - I do not guarantee it working and not destroying anything in your specific installation):

    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

    if /I (%1) == (wbemcntl.exe) goto SkipSrv
    if /I (%1) == (wbemtest.exe) goto SkipSrv
    if /I (%1) == (mofcomp.exe) goto SkipSrv
    %1 /RegServer

    goto End

    if not exist wmicore.exe goto End
    wmicore /s
    net start winmgmt

    After this was completed, I rebooted and did see the warnings happening about 10 minutes long again, but finally after seeing two informations with source LoadPerf in the application log about removal and loading of performance indicators for WmiApRpl (WmiApRpl) the health.xml file in C:\Inetpub\Intranet\health was created again and no more warnings have been shown.

  • Can you also see if running
    winmgmt /resyncperf
    can solve this problem?

  • Hi Donald,
    interesting hint - if I should see that issue again on one of my Home Servers, I will definitively try that first :-)

  • Thanks for the tip. It fixed my problem. Now I get the health.xml file generated and NO error entries in the Event Log.

  • Have seen another confirmation in the German forums, that this fix was working for the described issue.

  •   Worked for me too. Thanks for the tip... was driving me nuts having that many warnings on the log and WMC connector showing "status not available"

  • Did you try both fixes?  Do they accomplish the same thing?

  • Did you try both fixes?  Do they accomplish the same thing?

    I think, yes - with my more complex method I accidentially may have touched the problem cause, and Donald did show a shorter method to accomplish this.
