Cannot Install python-3.7.3-macosx10.6.pkg

[steve_314]

I cannot install the latest version of Python (python-3.7.3-macosx10.6.pkg) on Mac OS 10.6.8. The installer throws the following error:

The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)

Couldn't open "python-3.7.3-macosx10.6.pkg".

And leaves the following messages in the console log.

Any help appreciated.
