I have installed the MSBuild.ExtensionPack (From CodePlex) on our BuildServer, but when a build triggered by a Build definition I get the message: "error MSB4019: The imported project "C:\Program Files\MSBuild\ExtensionPack\4.0\MSBuild.ExtensionPack.tasks" was not found" I am completely sure that this path is right!
I can run the very same .proj inside in a command-prompt at the server with no problem, it's only when I try to trigger it as a build definition it fails.
(The .proj-file is located at the server, at D-drive if that's should matter.)
