The problem has to do with the assumptions in python scripts. See below values of variables which will not work as expected, 
i.e. installName = oldname.replace(self.archDir, self.installDir) will not do any replace.
Why you can’t reproduce it — i don’t know.

In any case, i have a working solution, so it’s not an issue for me and it is up to you if you want to further investigate it.
I just wanted to point out that this part of the python code does not work in all circumstances.

Regards,
Denis.
