WMI error

  Hofnar 16:00 16 Nov 04

After installing PC Accelerator on this months PC Advisor's DVD, I ran a scan on my computer. It nearly finished the scan but while checking the HD surface it stopped responding. Then it came up with the message : Optimization failed due to internal WMI error. No further information was given. Can anyone help?

re: WMI error
it is due to Windows Management Instrumentation you should be able to fix it by deleting
and then re-creating the files in the %SystemRoot%\System32\Wbem\Repository folder.

I've tried you suggestion but after stopping the WMI, I tried to find the %SystemRoot% folder. After over an hour I have failed to locate it. According to Ventanas there is a bug in the program. So I'll wait for the update I think. Thank you both very much.

It's not really according to me. It was TOPCAT® who took the trouble to discover what the problem was. I haven't loaded this, and have no intention of doing so.

I've found the Wbem file under Winnt (I am running XP). Deleted the files as suggested, but after all that the problem is still there. As TOPCAT found out it's a bug in the program.
Thanks for your help anyway.
