cant open app store on my mac book pro

And what happens when you try? Error messages? endless bouncing? Bounces then stops? Kernel Panic?

i have the same problem and with other apple apps

just boune once and stops

bounce

Launch Disk Utility.

Select your Macintsoh_HD Volume.

(Repair Permissions)

"Application can't launch" is the ONE time (Repair Permissions) can actually help.

Did you find solution for this problem sir? I face the same problem. Applications bounce and not open. Disk permissions dont work.
