I am trying to install SP2 for XP, and during the backup process for the registry, I am getting an error that it cannot backup HKCR\AppID....

I tried to change the permissions for AppID folder in the registry, but I get the message "Unable to display the user selection dialog.  Class not registered."  I then tried to take ownership, but I was not allowed to do that either.

Any suggestions??

Essentially, they put a null character into the key name.  The normal regedit tools interpret a null as end of a string, and so NEVER get the name right when trying to delete, change permissions, etc.

www.sysinternals.com has something that will fix this.  http://www.sysinternals.com/Utilities/RegDelNull.html
