Is your feature request related to a problem? Please describe.
I want to use leocad, but I also don't want to have to install it with the admin password.

Describe the solution you'd like
You could introduce a .zip file with all of the files the installer would usually create.

@Coderchris842 You can just download the exe and extract contents with 7zip - it's portable.
