I installed 3.4.1 on top of 3.4.0, Win 7, both 64-bit versions.

The installer is careful to only overwrite or delete files it installed. 
The only problem one will have is if you modify a file Python installed 
or add a new file where Python subsequently adds one (but that is 
unlikely in bug-fix releases anyway).

Delete \Programs to match what you should have.

I suspect you nailed it.

 >>> sys.executable
'C:\\Programs\\Python34\\pythonw.exe' (from Idle)

whereas the new 'C:\\Programs\\Python34\\lib\\site-packages' will be empty.
