PyInstaller on Windows 7 with Python 3

I have been using pyinstaller with python2 with no problems

Now I have upgraded to python 3 I am having problems

I am on Windows 7 with Python 3.6 and pyinstaller 3.3

When I run pyi-biuld, the process completes and builds a dist directory. The exe starts up and then crashes.

I note that there is a python27.dll in the dist directory

Is there something I can do to trace what is happening?

This is the pyi-build output for a minimal program

(wenv35) C:\test_pyi>pyi-build foo.spec
46 INFO: Testing for ability to set icons, version resources...
92 INFO: ... resource update available

I am now getting a Fatal error dialog:

Error loading Python DLL: C:\ ......\python27.dll (error code 126)

It appears that Python 3.6 is not yet supported by PyInstaller: https://github.com/pyinstaller/pyinstaller/issues/2286

Generally, this would have resulted in an error when compiling, but I imagine that if you have both versions of Python installed on your computer, it is finding 2.7 somehow and packaging that up, which results in your exe not running properly (mismatch between your python 3.6 code and the python 2.7 dll)

You may have to downgrade to 3.5 for this...
