Installed with python-3.4.3.msi first, then wanted a 64bit side-by-side )of course in an other folder)

Wanted to install python-3.4.3.amd64.msi, the first thing this one did is removed the 32bit install :-(

This is an issue with 3.4.3 only, and I suspect it was something funny in the build config that should just work with 3.4.4 - adding Martin to make sure.

Basically, the upgrade code in the 32-bit installer was (I think) the code used for dev snapshots. Both installers are supposed to remove dev snapshots, so the 64-bit installer will remove it.

If you install the 64-bit version first then you can have both.
