WampServer

Hi,

OS: WINXP
i´m trying to install PEAR with multiple PHP Version.
So I cd to C:\wamp\bin\php\php5.2.11 and start the go-pear.bat in this dictory.
The Batch starts and asks me system/local. The next step asks me for the file layout. I choose "1" but than it stops with

(german)
"Eingabefehler: "C:\Dokumente "" hat keine Dateierweiterung
witch means
"input error: " C:\Dokumente " got no file extension".

Can anyone help me?
Where does the C:\Dokument come from?

Thanks!
