Hi Terry, 1. The command py doesn't work. It gives me the error below : C:\Users\mchak>pyFatal Python error: init_sys_streams: can't initialize sys standard streamsPython runtime state: core initializedAttributeError: module 'io' has no attribute 'open' Current thread 0x00008290 (most recent call first):<no Python frame>
2. If I use py -0, I get two installed versions. However, if I try to uninstall from Control Panel, I see only 3.9 version C:\Users\mchak>py -0Installed Pythons found by py Launcher for Windows -3.9-64 * -3.8-64 3. I tried to uninstall v3.9 and reinstall but it didn't solve the issue.

The question is What is trying to use that? What installer are you using? I would (re)download the one from python.org. -- Terry Jan Reedy -- https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list
