It didn't work for me, It didn't give an error or anything but wormhole still isn't recognised as a command :(

Your Powershell is probably not using TLS 1.2. See

Would there be an easy way to package this, without installing all those toolchains on the target system? (choco, VC++ compiler, all of Python 3.x)

Edit: pyinstaller doesn't work:

PS C:\Python38\Lib\site-packages\wormhole\dist> .\wormhole.exe receive 1234-pass-phrase
Traceback (most recent call last):

Still working on fully up to date Win10. Had issues with the choco install -y vcbuildtools line so skipped it and was able to install and still run without any issues.
