I have the same issue, I downloaded the convert file and placed it in the place you said, tried to run it and it said :
3.1.4\texconv.exe" -m 13 -timing -nogpu -f BC1_UNORM -y *.JPG
No matching files found for *.JPG
Done!
I tried installing for the last 3 days, first with FTX Central , than downloaded manually and used FTX to install from the zip file.
Still getting the following error:
0:04:22.772 E/SYS: +-------------------------------------------------------------------------------
