Also, there is an .exe package that should be easier to install, and is recommended if you do not need single precision floats. If you still want the .zip package, then, assuming that you unzipped it in C:\, set the following environment variables: OPCODEDIR=C:\csound5\plugins OPCODEDIR64=C:\csound5\plugins64 it is also recommended to add C:\csound5\bin to PATH and PYTHONPATH.
