I adjusted your script (with credit) to work for my AMD GPU x64 users. I would have contributed to your page but I wasnt trying to mess with the original intention of your script, so I just made a copy in my repo..
Just wanted to link it here, to show you the changes I made to automatically get amdocl64.dll from AMD if it was missing..
Here is what I did for Radeon RX and Pro x64 users..
