Photoshop CS4 APPCRASH @ Startup Vista 32bit

Hi,
I've currently trying to fix photoshop on my company computer and I can't seem to get it to work. I've tried the following:
1. uninstall/delete files/reinstall
2. clear prefetch files
3. scan for viruses and registry errors
4. run as admin, run on different account, run in compatibility mode

My Computer is a Dell XPS1530 with 8600m GT. Photoshop worked fine for quite sometime and now it crashes with the following error after reaching "Building color conversion Tables"

Problem signature:

Any help would be greatly appreciated.

Thanks in advance,

see the FAQ. reset the preferences... i think it's the 2nd topic in the FAQ list (top of this forum list).

reset preferences Didn't work...

anyone know how to fix this?

This any good to you? <http://www.adobe.com/support/contact/cs4clean.html>

uhm thats for pre-release/ beta versions. This is a new pc and the software was installed directly from disc.

As soon as you have attempted an install there is a chance that residues of an aborted attempt will remain on the hard drive, hence the recommendation of the clean script.

:-) Thanks John - perhaps I should have mentioned that in my post.

Tried it. No luck there. Photoshop still crashes at "building color conversion tables"
