Windows 7: Problem installing Adobe CS4 software?

I just got CS4 in the mail today and when i went to go install it the Autoplay installer came up and asked me if i wanted to run the program. When i double clicked on the Ps icon a window came up saying "File Access Denied".

Can anyone help?

Thanks

I launched the setup directly off the disk (CS3). I can't remember but I may have just out of habit right clicked it and selected "Run as Administrator".

Otherwise the install was uneventful.

Thank you! this worked for me.

Can anyone give me some advice for a trouble free install who has CS4 Master on their system? My partner has just bought this and she has asked me to put this on our system. I put this on Vista x64 before I changed to Windows 7 Home Premium x64. I remember the only problem I had was that when I ran command promp as administrator it came up as adobe version cue in the cmd prompt box for some reason. I would just like to increase my chances of the install running smoothly with no hickups. It took about 2hrs as well and once it crashed on the last disk and I had to do it again so if I can avoid this then all the better.

I could easily do a custom installation to install everything else apart from version cue as we won't be working in a team environment or anything like that, we will just be doing some projects at home.

Also does it matter how many programs I have installed on Windows 7? I am concerned as this is quite a big package. I seen a thread on seven forums at some point where it talked about "how many programs do you have installed" but I can't find it anywhere or I would refer to it".
