Installing 4.0 + 3.0 deinstalled = Error

Hi, I deleted Parallels 3.0 on my macbook (Leopard) some month ago and I'm now trying to install 4.0 .
Though I deleted all files of the previous version the installation-wizard tells me that he has to deinstall 3.0 first.
The installation-statusbar completes very quick and after pressing the "restart to complete"-button a error returns (but no reason is given). There are no files installed after through the installation process...

Thank you for your help.
