I'm running csound5 on vista, and it runs fine from the csound5 gui, and I can also call it from python 2.5, I have both python 2.5 and 2.4 installed. However I'm unable to load it as a vst. I installed the complete version, under XP Pro I was able to load it as a vst into fruity loops, but now under vista its not recognized. I can still run csound5, but just not as a vst anymore.
