I bought World of Goo last night at Walmart and just tried installing it on my laptop however it has been having troubling doing so.  My laptop easily has all the requirements for installing and playing this game.  It tries to install it, but after about 30 minutes of trying my computer displays the following error:
Cannot prepare main package
Probably corrupted package, incorrect TMP/TEMP variables or there is
no execute permission for temporary folder.

Once the error is displayed, it stops trying to install the game.  Any ideas on what I need to do?  Thanks so much in advance.

Edit:

OK!  I got it to work.  Instead of trying to get it to autoplay the setup file, I opened the CD and copied the setup file directly to my hard drive.  Then I tried using that copied setup file to install the game.  It had no issues after that!
