Thank you for the answer. But i have installed the LWP Module that ist part of the libwww-perl on active state. I have unziped the file
by copying the LPW folder in the zip archive into my /lib folder where the other Modules are.
The file UserAgent.pm in the folder LWP does exist. Im copying the Folder only because i can't start the ppm manager on the computer which needs the LPW Module because it is in the intranet. But i think, that copying the Modulefolder would be enough or i'am wrong ?
