Hmm, this is a quite strange problem and I'm not sure if it's really a fault in HWiNFO.
It seems to crash in system calls when it tries to retrieve the system default font.
Is the Windows installation OK, are there no issues with other applications?
Sorry, I don't know what exactly to do. Best would be to reinstall Windows. Or try to make some changes to appearance in Windows like themes, etc. maybe that will re-initialize the fonts.
