[issue22177] Incorrect version reported after downgrade

[Zachary Ware]

Zachary Ware added the comment:

'python.exe' in the installation folder doesn't really matter -- it's just a tiny executable that embeds python27.dll, which contains the interpreter and is installed in C:\Windows\system32.  I suspect the installer didn't downgrade python27.dll because the installed version was newer.

As for your issue, such an in-place downgrade isn't quite supported (as you see), nor do I think it's a particularly good idea.  You should be able to achieve your goals with much less headache by uninstalling 2.7.8 completely with its own installer, then installing 2.7.5 where you want it.

Steve: is this something that would be easy/worthwhile to support in future 2.7 installers?
