b=2021, k=1, n=67 (from table above)

No, I thought it was clear, I got my own work: 158 hours of my work here and you're unable to run WinPFGW?

You're testing to n~1500, which is done in seconds with pfgw. I don't know which program...

I'm running pfgw on Win 10 here, too (and Win 7 Pro on others).
