I'm using Windows 7 64-bits and downloaded your custom release.
That shouldn't happen, as the video patch has been applied to XP, Vista, and 7 executable. You could try patching it again by downloading here:

Our version uses the sound fix because some of the audio is really messed up without it on Windows Vista and Windows 7. If you're playing on XP, you can delete the sound patch file, Mss32.dll, and the audio will still be fine. Unfortunately, the sound fix does have bugs (some clicking sounds as you described), but again, it must be used in Windows Vista and Windows 7 for the game to even have correct sounds. It just clicks and is messed up without it when running the game in Vista or 7.
