Yeah, OK, I can say that I tried installing 3 things, two were for V4 and the other was some environment-related item. 

The app asked me where I wanted to install the V4 items, and I told it to put them into the folder called "V4 use".  It installed accordingly, with readmes in your default location. 

No issues.

I would take care about the temporary folder though.  I think that extra stuff was cached there (inadverdently for the original distro), and that's how I could see it.  Apart from that, can't see it working incorrectly.
