Maybe everyone else knew the solution, but I couldn't find it in the forum.
I wiped my laptop back around the holidays and installed a clean Win 10 Pro. Then installed a clean Creator 3.3 CP1. There is a chance I skipped some approval dialog accidentally.
Today I needed to use my MiniProg3 for the first time and Win 10 failed to find the a driver so both Creator and Programmer refused to work. I searched the forums to no avail. I had noticed something about 3.3 SP1 not showing up in updater. So I downloaded it and installed it. Still no joy.
I browsed around the cypress installed tree and found a drivers directory in the programmer sub-tree and a couple of windows batch files: driver and DriverUI. I clicked on 'driver' and it installed the drivers and now everything is working fine.
So just a heads up if anyone else runs into this problem.
I recently updated to Creator 3.3 SP1 (not CP)
