Even at the stage of analysis of setup ini I was alerted by the fact of 4 repetitions of the same operation (namely, Copyfiles). Any interpreter on the second reading will block the operation, because it repeats the previous one (namely, there will be errors in mkdir (creating a folder that already exists)).
And this will be the answer in any version of Linux or Windows (I can't answer for Mac, because I have no experience with it).
How you managed to run and install VN is a mystery to me.

Another option I will try (manually repeat the registry code because after installing it I get 2 parts of the broken registry entries).
This is symbolized by empty lines of his entries, duplicated in both parts of the registry.
Windows 7 and this registry behavior (it looks very much like your operating system has fallen in two pieces). Which made it possible to run and install VN.
If after manually writing the registry VN will not start (the given version of VN is not repairable).
