@ttspace I think this is an issue with the VS installer not cleaning up registry keys properly. We've seen things like this in the past.

Can you verify that the following folder exists on your machine? C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python39_64 This is where VS installs python.

If python isn't there, there might be stale registry keys that VS uses to check for existing installations. To fix the registry, do the following:

1. Run Start -> regedit
2. Delete Computer\HKEY_CURRENT_USER\Software\Python (this will mess up any other python installs you have)
3. Delete Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Python (this will mess up any other python installs you have)
4. Run VS again and modify your installation. Python 3.9 should now be unchecked. Check it and click on Modify and it will be installed.
5. Now verify that the following registry entry exists: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.9
6. Verify that the installed python is actually on disk at C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python39_64

I did these steps and I was able to run python applications using the python that comes with VS.

@AdamYoblick I didn't do anything else, python is here.

1. Computer\HKEY_CURRENT_USER\Software\Python does not exist.
2. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\3.9 It exists.

I don't see the exact same error message from pylance, but I AM able to repro the Python was not found messages, even though the environment is able to be created successfully. Let me investigate.

@StellaHuang95 can you try to repro this whenever you have some time? I just want to make sure this isn't an urgent blocker now. Thanks :)

[StellaHuang95]

@AdamYoblick I saw a bunch of Error: Unknown change event received, but I wasn't able to repro the Python was not foundmessages

[AdamYoblick]

Does the environment still get created? Unknown event received seems like a pylance issue, we probably need to present this to the team then.

[StellaHuang95]

@AdamYoblick yes

[AdamYoblick]

Ok great, doesn't seem too urgent then. The error messages are annoying and we need to fix them. But the callstack concerns me, that's a pylance problem. Either there's a bug in pylance, or PTVS is sending something it shouldn't be. Needs more investigation.
