#707 pywin32-32 fails to install on Win 7-64/Py 3.5-32

[Mark Summerfield]

I installed Python 3.5-32 on Win7-64. But when I tried to install pywin32 the installer popped up a "Cannot install" dialog saying "Python version 3.5 required, which was not found in the registry".

Of course, it is possible that the Python 3.5 32-bit installer is at fault (i.e., maybe it hasn't updated the registry--although I used admin privileges and did an install for all), but I don't know how to discover that.

The packages I used:
python-3.5.0.exe
pywin32-219.win32-py3.5.exe

I have exactly the same problem. Is there a solution or a workaround?

Same problem. Uninstalled Python 34 and installed Python 3.5-32. Still get the error message.

Re Mark's comment -- I tried exporting the HKLM Python 3.5 registry branch and importing it as 3.5-32 to help the installer find it. No luck. Argh.

There is a work-aroud: modify

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\3.5-32

to be

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\3.5

and your installation will be succesful. Then just return the key name to be "3.5-32". Whether there will be any side-effects I cannot tell yet - I am just a rookie with Python (but messed with Windows for tens of years...)
