The below patch fixes the install script. Probably not the most correct one but gets the work done.

I tried to follow your instructions from ArchWiki but noticed that this package is broken in three ways:

1 - Requires VCRUNTIME140.dll but this is not mentioned anywhere

2 -

[andreymal@wsl ~]$ /opt/wsl-hello-sudo/install.sh
No built binary was found. Build first before installing.

3 -

[andreymal@wsl ~]$ cd /opt/wsl-hello-sudo/
[andreymal@wsl wsl-hello-sudo]$ ./install.sh
[1/6] Installing Windows component of WSL-Hello-sudo...
[...]
+ chmod +x build/WindowsHelloBridge.exe
chmod: changing permissions of 'build/WindowsHelloBridge.exe': Operation not permitted
[...]
[5/6] Creating uninstall.sh...
./install.sh: line 178: uninstall.sh: Permission denied

This error means I have to copy /opt/wsl-hello-sudo/ somewhere else, which makes this package practically useless
