I have had problems recently when trying to install some downloaded software, whereas when I select install/run, the setup does not initialize and the setup.exe just disappears all together. I can not locate the setup file nor is the program installed. I have performed a search of all folders and it is no where to be found. The latest such program I've tried to install is DivxToDvd 1.99.

I am using WinXp Pro w/sp2 and updates. Has anyone had this issue with any software setup.exe and if so, what was your solution?

Thanks in advance.
