Disregard my last post (or just delete it, pls).

Ok, I got this working on 32bit and 64bit IDA Pro v7.2

1. Install Latest Python 2 Release - Python 2.7.18
From here:
https://www.python.org/downloads/windows/
Installer: python-2.7.18.amd64.msi
2. Once installed add c:\Python27 to your OS path.
3. Run cmd.exe as administrator
4. Goto c:\python27\scripts:
5. Run:
pip install keystone-engine --pree
then
pip install six
6. Save latest Keypatch.py from here:
https://raw.githubusercontent.com/keystone-engine/keypatch/master/keypatch.py
7. Copy to \program files\[your IDA Pro install DIR]\plugins
8. Load IDA Pro and check for "Ctrl-Alt-K", and check for errors.
9. Load test .EXE file, highlight a function and use ctrl-alt-k keystroke to load keyPatch
dialog.

That's it.
