Hello, I’m the creator of that tool. The win64 build is very recent so I wouldn’t be surprised if there are a few issues with running it on different machines (also I haven’t set up any sort of code signing so the application might be flagged as unsafe by the OS). I can help you out troubleshoot if you’re interested in some help!
The application uses a ray tracing rendering technique, so it needs a fairly good GPU (also not sure it would run on a VM due to the GPU driver layers), but we can discuss details of your setup by email as well: phototiler@gmail.com.
