Install and Uninstall error

2007-10-29 05:49:34 by TOPO

I have installed PDFCreator on Windows Vista with the *.msi package downloaded from this site. When I try to install or remove it, I get this dialog-box box:

'There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor'

I downloaded the gpl file, but I cant install it because it says I have this other package installed....

How I can remove and or install PDFCreator?
Thanks,

Tomas
