I recently uninstalled support assist for a reason, Now I could not reinstall it back

I used 2 launchers which were provided by this site

When I use the "SupportAssistLauncher.exe", it shows that SupportAssist is only for PC's from Dell and Alienware

When I use the "aulauncher.exe", It downloads an update file called CSAW.exe for 5.5MB and then says Installation is completed.

Both of these did not do any changes, this happens again and again even if I restart my laptop

My Laptop Model:
Dell Inspiron 15 - 3567
Processor: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz (4 CPUs), ~2.9GHz
