Try using your default Aero skin when you install. Also, try right clicking on the install.exe file and choose 'run as administrator'.

Try copying it to your desktop and run it from there.

I believe WindowBlinds is causing the issue.

Open Windowblinds and set it to the original windows desktop. That will basically unload Windowblinds. Once it's unloaded, you should be able to install it.

Hi CarGuy1, using the first windowblind now and noper, that didn't do it.  It did exactly the same thing again.  Thank-you

I go to Autoplay, a blue/grey rectangle pops up with an Install Adobe Photoshop CS4 button. I press tha and a box open for permission to open. I click yes. It seems to want to start but still goes transparent.....

RedneckDude, I installed a PS setup-shortcut on my desktop bjt, it also did the same thing.   Thanks

Could it be going somewhere else? On a couple of occasions, I was told there wasn't enough space. But, I believe I have more than enough.?

Are you sure the files on the cd are not corrupted?

If you can't install from that cd, is it possible that CS4 has a protection built in to prevent installation from a cd not from Adobe?

IROKONESS.... if you are in the W7 default aero skin, right click on the windowblinds icon in your systray and close it (exit windowblinds).

Then try the Administrator installation I advised above.

Irokoness, All the above information above are things that at least one of them should work. I had your problem once and finally got it to install. What I did was copy the entire contents of the disc to a folder on my computer. Go where ever you keep your folders and make a new one called PSsc4 or whatever you want to name it. Then copy the contents of the entir CD to it. Now you can take the CD out and go to your folder. Somewhere in there you have to see, autorun.exe - photoshop.exe - setup.exe - install.exe. Double click it and it should install PS. If you don't see any of these then it's a no go for sure. I also don't know if it's an orginal PS disc or PS contents copied to a regular disc. If it's a regular disc then something is missing from it which can happen sometimes when copy from an orginal. I don't have any other ideas so this is my last shot. If by chance you aren't sure how to copy the disc to a folder on your computer email me.

I just tried to open CS4 Cleanupscript and it also stopped before opening. This is after I give my security permission to open. Could it be my Norton 360??

Just saw your suggestions and will apply them directly. Thank-you. 

Here's a possible cause. When I had PS 7 loaded then installed a trial of CS5 there was a problem after the trial ran out. PS7 no longer worked because the uninstaller I used took out files relevant to PS 7. I thought the uninstall took out all the files when it really didn't so I tried reinstalling PS7 and that didn't work. I had to go in and delete all those remaining files then do a clean install of PS7. Could be there are leftover files if she was using an older version of PS. If so she'll have to go in and delete them. Could that be causing it?

I would try RNDs suggestion of copying the entire DVD to your hard drive in a temp folder and running it from there.

Since there's  no reference to if it is a store bought DVD or a backup, copying the files over would rule out any disc issues. If it copies, the files are probably fine. If it errors out, than the CD player could be dirty, a misaligned laser, or a bad DVD burn.
