Hi Ramesh,

That did the trick.  For the record:

  1. Used msconfig to switch to safe mode boot
  2. Booted to safe mode
  3. ran cmd.exe as an administrator
  4. typed "cd C:\Windows\System32\LogFiles\WMI"
  5. typed "rename RtBackup RtBackup2"
  6. Used msconfig to switch to normal boot mode
  7. Reboot and found event viewer working

Thank you! 

Rung

Hi rung_windows7,

Renaming or deleting the following folder seems to work for some users:

C:\Windows\System32\LogFiles\WMI\RtBackup

REF: Event log error 4201 - ERROR_WMI_INSTANCE_NOT_FOUND (a helluva great thread)

    Those answers to my problem could possibly work however there is a requirement to run a disk containing security settings on our machines.

    The disk was made I think for Win XP so the settings created some problems on the Win7 machines a new disk was created and this problem was fixed.

    Thanks for your suggestions and help.

    Hi - sorry, read your post right now. So the only thing i have done was:

    1. start regedit on machine where eventlog works
    2. navigate to the different registry paths
    3. right klick each and select export, save the files as "selected subtree" anywhere on your hdd as .reg file
    4. put in on an usb stick or somewhere else
    5. start the machine where eventlog is not working and double klick each .reg file to import in current registry
    6. restart the machine, eventlog should work now as expected

    that's all

    until now, had no issues on my target machine
