Getting (Error 4) why trying to run CorelDraw X5

After installing, and trying to run the software i get the following message:

Try restarting your computer and then restarting the program. If these actions do not solve the problem, try uninstalling and resinstalling the program (Error 4).

I have done both the actions, restarting and uninstalling, but i get the same error.

I have also clear the temp-direcotry. Deactiviate the antivirus-software is not possivbe (password-protected).

The antivirus software is mcafee

Windows XP with SP3

Any ideas ?
