--- Comment #2 from Hans Leidekker hans@meelstraat.net --- The dll is installed if I comment out the 'w_call dotnet30' step. It turns out that XPSEP installation is not needed on current Wine; dotnet30sp1 installs and verifies successfully if I comment out that step. I'm not sure if it's worth digging down further into dotnet30.
