I run the installer, wich begins to extract neccesary installation files. It finishes, and then nothing happends. Oh well, not really nothing, I see a flash on the screen wich might be the installation program, but nothing happends. When I installed .NET Framework 2.0 SP2 I was told to install another update wich would improve compatibility, but I didn't do that. Could that be the cause of my problem? I also have the Swedish version on Windows 2000, while your version of .NET is in English/Japanese. Can I use Microsofts standard language pack for language support? EDIT: I checked the temp directory, and the PdnSetup folder was empty, even though the installer clearly extracted files to it.
