Can't open processed files from flash drive to pc

Working on a MacBook Pro I have processed shots with Topaz. Afterwards I transfer images to a flash drive. I insert flash drive into my pc. Transfer images to my pc. When I try to pull up an image I get this message;

It looks like we don’t support this file format

What program are you trying to open them with? Do the files still open on the Mac?
