QBPE 3.6.0 compiler error

[bplus]

What I would do:

Delete all previous 3.6 download attempts.
Download fresh.
Extract to your Desktop where you don't need setup permissions to use.
Do not white list.
Run the QB64pe.exe from your Desktop.

But I don't know what you did with Windows security, I'd try and undo it if the above does not work.
