Hi,
After unclean uninstallation of some software (read: symantec), the following registry entry may
contain bad (i.e. no longer existing) path to a DLL. With this in place some programs (notably,
old 16 bit code) fail to start. Cleaning the value manually (just dropping it) seems to
resolve the problem with those programs, so CCleaner could have done that, automatically,
yet it did not bother to even complain.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD

Hope this will be taken into account.
Cheers,
