I installed Pro-Tools on my E: but it went ahead and installed the bundled plug-ins to C: which I don't use for anything other than Windows. If it "just doesn't work that way" then it just doesn't work very well in that regard.

I'm sure it can be done. Even if it requires a change in the registry. Somewhere, Pro-Tools is reading an instruction that says "hey, the plug-ins are located here" but one tiny drive letter has to be changed to convince it otherwise.
