I prepared to upgrade the Wacom Intuos Pro tablet by uninstalling the existing driver per Wacom's support. The uninstall process hung the computer for over an hour. I forced a power-off per Wacom's direction. Retried uninstall and similar behavior. Wacom can't/won't help and I can't get beyond first level support.
All this left me with a screwed up registry entry key "HKEY_CLASSES_ROOT\Wow6432Node\AppID\npWacomTabletPlugin.dll". If I go to the key I get an "Error Opening Key": "npWacomTabletPlugin.dll cannot be opened. An error is preventing this key from being opened. Details: The system cannot find the file specified." If I try to look at the permissions for the key I get "The requested security information is either unavailable or can't be displayed." If I try to export the key I get "Export Registry File": "The selected branch does not exist. Make sure the the correct path is given". If I try to delete the key I get "Error Deleting Key": "Cannot delete npWacomTabletPlugin.dll: Error while deleting key." I tried Sysinternals' RegDelNull. It did not show the key as having nulls.
I wasn't thinking while waiting for Wacom's response and let any Restore Point slip off the end.
I can manually recreate the values in the key if I can just delete/re-add it. Any ideas how to do that?
The Win7 64-bit computer works except for the tablet. "Programs and Features" shows the "Wacom Tablet" v6.3.7-6, the "Web Tablet FB Plugin 64 bit" v220.127.116.11 and also the 32-bit plugin.
