I am running Window 7, 32 bit machine, home edition. I am having trouble erasing a key from the registry. the key in question is 'Acronis'. It is found in HKEY_LOCAL_MACHINE > software. When I bring up the key, Acronis, and try to delete it I get the message 'cannot delete Acronis. Error while deleting key.' I have tried using many registry clean programs to solve this problem but nothing works. Rebooting does not help. Any ideas out there?
