Well, thanks, daxim. This shows that I am not the only one with this problem... Unfortunately enough, I don't know how to read the code of the post. It looks like a diff-format of some kind, but this goes far beyond my level. I tried to force-install the package. The installation was appended, so this is good enough for a first approach, I guess. As said, I develop on Apple and this whole exercise is there to port my software to Windows... Thanks for posting this! Bas
