WebMethods installer 601 with script file

Hello,
when trying to use an installation script created by webMethods Installer 6.0.1, we’re faced to an explorer window asking to “Select Console Installation to Upgrade” (we have a screenshot if needed …).
Since it’s a new installation on a clean windows 2000 with a full .zip image of the entire 6.0.1 suite, why are we asked to upgrade something ? What do we have to chose as a file or directory to continue the installation process ?

Here is the content of the installation script we use, chich has been created by Installer when we made the first installation :
