Setup of PSP X5 Trial fails

[Emanresu]

I have downloaded the trial from the Corel homepage and I'm not able to install it, the following error message appears:

Ihr System wurde nicht geändert. Um die Installation zu einem anderen Zeitpunkt vorzunehmen, führen Sie die Einrichtung erneut durch.

Google translation:

Your system has not changed. To perform the installation at another time, please run the setup again.

OS: Windows 7 Ultimate x64

I have cleaned up %temp%, tried to install with the run as administrator option,, as well as under the local administrator account.
The error message remains.

Have you tried creating a new user name with admin rights and then redownload the trial and install on that new user name?

I have windows 7 Ultimate X64 and I can install PSP X5 but when I try to install creative collection (brushes) I get an error box. It has been driving me crazy. It installed fine on the computer that has XP Pro on it but not Vista or Windows 7 Ultimate.
