So this only applies to when a CD has an autorun feature that will pop up an install screen (usually a square window in the middle of the screen)?
Very strange.
This "install screen" that is appearing is just a simple program that gives a window. It generally should behave the same as any other program that runs in a similar fashion, however - it doesn't do it to any other apps...
... I would suggest that there is a problem with the "autorun" feature. Difficult to know where to start for a solution to this one.
Firstly, close the program.
Then RIGHTCLICK on the CD DRIVE in MY COMPUTER, and select EXPLORE from the drop down menu.
Now go in, and run the SETUP program directly.
See if the program now behaves properly.
