Yes, that's why @fa201 advised to use the user account and not the administrator account to run the installer.
The installer will ask for admin permissions. You have to grant them, either by simply accepting, when the user is in the Administrators group or you will be asked for username and password for a valid administrator account.
Then the user should be able to run LibreCAD without admin privileges.
