Can't set Ifilter debugging on Vista. Regedit HKLM\Software\Microsoft\Windows Search\Gathering Manager:DebugFilters results in error "Error writing value's contents"

Question

Can't set Ifilter debugging on Vista.

Per instructions at

http://blogs.msdn.com/ifilter/archive/2007/02/06/debugging-ifilters-with-wds-3-0-and-windows-vista.aspx

... I use regedit to set

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

to 1, but when I click OK, I get message results in 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" grayed out... however I can check them. When I click OK to save that change, however, I get error message "Unable to save permissions on Gathering Manager. Access is denied.

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.
