For windows PCs you need at least windows 7. The game itself shouldn't be demanding on system resources, in task manager it takes around 100 MB of DRAM, around 40 MB for VRAM and around 1-2% of CPU utilization on my Ryzen 7 (although when viewing the main menu animation it will use more CPU resources as the video format decoding is done by the CPU). Essentially it really shouldn't be an issue to run it if you have a PC that runs at least win7. It's why I don't believe the problem you are experiencing is tied to the game directly.
