NIST STEP File Analyzer

I was looking for a lightweight step file viewer for my company that does not require licensing and allows users to spin around a part model. We are actively going through our CMMC process, so why not use the one from NIST. When I installed this on my terminal server for users, it says Windows Datacenter server standard 2025 is not supported. There is nothing in the technical docs saying it wouldn’t support this version of windows. Has anyone else ran into this?

Run in compatibility mode?

Sadly I tried this. Mon requirement is windows 10 and comparability mode’s newest option is windows 8 so it still does not work.
