Problem uninstalling MS Office 2007 Trial version

Hi all,

I've just bought a Acer computer with XP pre-installed and also there was
Office 2007 trial version installed and ready to use.

Now I want to uninstall Office 2007 since I do not want to use it. But I get
a error when trying to use the Remove under Add/Remove Program in the Control
Panel.
The error message is something like:
"Setup error: The language of the installationpackage is not supported by
this system".

Now, how do I solve this?
There were no CDs with the computer, everything was pre-installed, so there
is no way for me to "re-install" it and then uninstall it.

Thankful for urgent response!

Sincerely,
Andreas
