I can confirm that there is a bug around. I solved it by installing all necessary program with build 1970 and then using that .hdd image when upgrading to build 3188. Have you tried this?
(It seems as if programs installs unproperly when using the current builds. The reason for this is, of course, a hidden secret of the Parallels desktop developers. They ought to be aware of this by now!)
Of course, this may be of no use to you, since you´re using Boot camp and not a .hdd file.
