Unable to install Office 2007 Beta

[Dorte]

Installing Office 2007 Beta from CD never really seems to start.

An installation window pops up telling me to wait while setup prepares the
necessary files... Apart from that nothing happens.

The setup log ends like this:

A "SetupTempKeyFile.tmp" is created in the temp directory with a size of 0.
It disappears when I kill the setup process.

Anybody having a good idea to solve this?
