Greetings Nicolas,

To figure out exactly what's going on here, click Start, then Run, type "eventvwr.msc" and
click OK, click Application on the left-side, then look for Error's from the "MsiInstaller"
source.  The most recent one should be it, assuming you haven't had any other problems with a
Windows Installer. Double-click the Error, and look in the Description field for a more
accurate description of the problem. If you post this description (there may be multiple
errors in the Event Viewer, so post all of them), we may be able to help much more easier.
