Installer for windows sets path/environment variable wrongly on Windows 11.

[SkybuckFlying]

1. First of all the installer defaults to "no", do not automatically add, which is weird for a default setting.

2. Second, I set it to yet add it automatically and it did it wrong (in windows 11 environment settings):

It added this line of text to "PATH" variable which is WRONG:

set LIBCLANG_PATH=G:\Tools\LLVM\bin

it add:

G:\Tools\LLVM\bin

3. It also fails to set an additional environment variable properly in windows 11 environment settings:

LIBCLANG_PATH=G:\Tools\LLVM\bin

This should be fixed it will help people who don't check these kinds of things and they might be baffled why it's not working on windows 11...

(At least I think this is what happened, there is a 0.01% chance I did this myself, but I don't think so... I was busy with other settings though, but I am pretty sure the installer did it wrong, it's kinda rare to see installers do this kind of thing wrong, you know...)
