What size hard drive(s) do you have? When's the last time you did a malware scan? SC Tom

Hi, I suppose the reason is that if the application uninstall information doesnt include an install date or application size information, the guessing game continues. Add/Remove Programs searches the Program Files directory on all drives in a manner similar to the Start menu. It looks for a directory name with at least two words in common with the application name. If it still cant find anything, it looks in the root directory of all drives. The winning directory establishes the application size. The creation date is taken as the application install date. Remember, you can have Windows avoid this disk search by simply registering the application install date and size as part of the uninstall entry.
