Photoshop won't open

[eti]

As of today, Photoshop CS4 won't open. When I try to start it, I see the blue circle going round for a few seconds, then it stops.
In Process Management a Photoshop CS4 will sit, using only 120 kB, doing nothing. I cannot end the process. When I try to start CS4 again, the same thing will happen and I have two copies of CS4 sitting in the process manager.

I tried to set my computer back to two days ago. To no avail. I then deinstalled and reinstalled Photoshop. Still to no avail. Anybody know what's going on?

On a hunch....Have you updated all drivers and checked to see if Photoshop has updated to Win 7 32 Bit?

Okay, I'll see how I update drivers. But how do I do that, from within Photoshop (which doesn't run)?

Anyway, I just managed to open Photoshop... from the default Windows viewer. It just won't open from the Start Menu. Still weird.

I'll see if I can update the drivers.

Nice little tutorial on driver install.
Another way is to go to manufactures web site and download driver there.
Photoshop can be updated by opening the software program and go th Help and toggle down to updates.

Post back if more help needed.

Okay, I updated from within Photoshop, that failed because I had two dormant copies of Photoshop sitting in my processes.
So I rebooted the computer, hit 'Photoshop CS4' from the Start Menu and it worked!

So thanks a lot!
