Axiom Home Page Forums General Discussion Technical Questions Error opening program

2 days ago i upgraded (reinstalled) Win7 and Photoshop cs4 could not be started anymore.
i reinstalled Ps. with the same result again.

Yesterday, i reinstalled Win7 again and then Ps. again.
same result.

every time i try to start Ps. a notice says: Photoshop was unable to start correctly (0xc000007b).

i looked that kind of error on the Internet and there are many answers, both complicated and simple ones.
One of them said that most probably the reason was in component services/services (local) there was a badly configured service.
I reviewed all the services and think they're ok.
then i uninstalled Ps. and cleaned up everything in the registry that pertained to Ps, as also on C drive.

then i reinstalled Ps, but i still can't use it.

the only thing left for me to do is to wipe C drive and reinstall W7 and all my programs; something i don't like to do;

does anyone have a solution to make that Ps. work?

Is that version compatible with 7?

I hear that when you play a Windows disk backwards, you hear Satan.
However, even more scary is that if you play it forward.... it installs Windows.

Seriously though.
Could be a 32 bit vs. 64 bit issue. Which versions do you have?
Also is it a legit version? A buddy of mine had issues with cracked 64 bit Ps and had to 'purchase' the 32 bit version for his 64 bit OS.

both Win7 and Ps are 64 bit versions and they worked well together (for more than a year) until 2 days ago when i reinstalled W7.

When you re install an OS, even the same version from the same CD, you are often likely to upgrade drivers that may have otherwise been left at an old version. Perhaps it is not so much Windows itself but a new, less compatible, version of a driver. Video card being the first I would check. You could try rolling back any possible suspects.

That's all I will make uneducated guesses at. Some experts will show up soon.

Did you install all the updates for Photoshop?

yes, i have installed the latest update for Ps, quite a long time ago.

But you've reinstalled Photoshop since installing the updates?

How would you update it if you can't open the program?

it's easy, i install Photoshop and after that i install the Ps. update.
it's when i try to open it that it does not work.
