Thank you "SandeepP" for your response,
For many months I have assumed "Click to Run" Office was a 64bit install on a Windows 7 x64 PC.
RevoUninstaller (free portable) does not recognise 64 bit programs AND the virtual "Q" drive had me bluffed.
There are many threads on the web by people with sticky "Q" drives. All my agony for nothing.
If I had only looked at the "C:\Program Files (x86)" to see "Click to Run" Office is 32bit even on my x64 PC
Uninstalling MS Office 2010 "Click-to-run" was sooo simple !
... Even the virtual "Q" drive has disappeared.
I did download the latest RevoUninstaller v1.9.5 portable
to replace my v1.9.0 from 5 months ago
and it worked a treat on both 32bit and 64bit PCs.
Even the Office program files/folder is gone. When I get some time I will run CCleaner -- I am very cautious about what I let CCleaner "delete",
preferring to white list files I don't recognise or understand -- blanket deletes are suicide !
Thank you for setting me free
