They supply install help for legit owners. They will also tell you if the version you have runs on Vista.
I recently installed a "legitimate" copy of Autodesk Auocad, a 1.3gb design programme. Unfortunately it did not work. There was no uninstall with the programme and Vista would not uninstall. This has happened before with smaller programmes and the only way I have found to get rid of the programme completely is to delete all the files and then manually delete the associated files from the registry. Not ideal but it works. Unfortunately this programme has many hundreds of files ALL of which are not "owned" by my login, ( stand alone PC for me only so why Vista does not know this is still a major mystery to me), so I have to change ownership and permissions to my login name and then delete!!! I looked at deleting "Hives" but that option only applied to ALL of my software programmes. I do not want any 3rd party registry cleaner so please do not offer. I am looking for a solution which will let me change multiple keys and sub directories "Ownership" and "Permissions" at one time.
I am running Vista Home Premium SP2
Intel Core 2 Quad CPU Q6600 @ 2.40 Ghz
2 GB Ram
on a Packard bell standard box
