Request a 32 bit version of Affinity Photo be released for Windows 10.
I have an admittedly old PC, but it is a 2.2GHZ, quad processor that I am sure could handle Affinity Photo.
AMD Phenom 9500 Quad-Core Processor, 2200 Mhz, 4 Core(s), 4 Logical Processor(s)
I recently upgraded my Vista system with a clean install of Windows 10 mostly so I could run Affinity Photo. My mistake for overlooking 32 vs. 64 bit.
I am running Affinity Photo on my laptop and would prefer to run it on my desktop also.
