Short version: wininst-14.0-amd64.exe has "-32" in it. It shouldn't, should it?

Longer version:

Running "python setup.py bdist_wininst" gives me a file named like:

project-version.win-amd64-py3.5.exe

When I run that, I get:

Python version 3.5-32 required, which was not found in the registry.

My "fix" was to edit the wininst-14.0-amd64.exe and replace the "-32" with 3 null bytes.

Pillow-3.4.2.win-amd64-py3.5.exe fails to install due to this. See <https://github.com/python-pillow/Pillow/issues/2285\>.

MS_WIN64 is never defined at https://hg.python.org/cpython/file/v3.5.2/PC/bdist_wininst/install.c#l157 because bdist_wininst does not depend on the Python headers. A possible fix is to use _WIN64 instead of MS_WIN64.

[cgohlke]

The attached patch was tested with Pillow-3.4.2 on Python 3.6.0rc1, 32-bit and 64-bit.

It would be nice to get this fixed in Python 3.5.3 and 3.6.0.

[zooba]

Thanks. 3.5.3 is definite, I've pinged the release manage on the original bug to see about 3.6.0, but definitely 3.6.1.

Considering we've gone through all of 3.5 and 3.6 with very few people noticing (and as far as I'm aware, completely able to fix it themselves), it may not make the initial 3.6 release.

[zooba]

Fixed for 3.5.3, 3.6.1 and default against the original bpo-26071
