Can't set Ifilter debugging on Vista. "Error writing value's contents" on Gathering Manager:DebugFilters


I am unable to set Ifilter debugging on Vista as per these instructions.

I used regedit to set

HKLM\Software\Microsoft\Windows Search\Gathering Manager:Debug Filters  

to 1, but when I click OK, I get this error :

Cannot edit DebugFilters. Error writing value's contents.

I tried changing the permissions on the registry branch -- it does appear to be a permissions issue. The Administrators entry has "Special Permissions" checked, and the "Read" and "Full" greyed out. However, I can check them but when I click OK to save that change, I get this error:

Unable to save permissions on Gathering Manager. Access is denied.


Solution

  • I found the answer. You have to right-click the registry branch "folder", choose Permissions, then Advanced. On the Owner tab, set yourself as the owner. This lets you change the permissions.
