The DLL version does not match firmware version can be a serious issue however and I’ve seen controllers not recover from that issue. Make sure you are using software provided by HPC and NOT the software linked by @JBxrayman on the Nottingham Hackspace website.
The best place to get your files for a HPC is either through HPC laser or you can try this link below:
Let me know how you get on. The links provided by @JBxrayman was not written by me or anyone working with JAS or Smoke & Mirrors. It was created by the Nottingham Hackspace and links to files specific to their laser cutter, setup and firmware and might not be especially useful for you.

I’ve found that Windows 10 and it’s constant updates and lasercut5.3 don’t make great bedfellows but it does work adequately. But once you have the software communicating with the laser cutter you should be fine.
It might be helpful to ensure you run the software compatibility wizard also for Lasercut5.3 and it’s associated drivers.
