The current version 0.4.0 absolutely works on win7 pro. I have it on 3 different PCs. I have noticed that for some radios (like the Baofeng B6) you have to do a "read" operation before it will let you do a write as the com port is set when Chirp reads from the radio. I have always seen the comm port greyed out on write.
You may also have a problem with your programming cable. I assume your radio is on the list of those supported by Chirp.

What build of Chirp do I need to us for windows 7 pro. I have tried all the
versions I can find and each one does not let me download to the radio. It will
not show a com port number in the window at all. I really need to work
this out.
