You don't need to buy a license unless you're using HWiNFO for commercial purposes. But if you want to help with support, it's up to you
I'm sorry, but I don't have information how to support this proprietary technology. I tried this in the past, but didn't succeed yet. If you would attach the HWiNFO Debug File, I can have a look if I perhaps can see something, but chances are rather small.
Using a *.key extension could be problematic with some e-mail clients or anti-malware software. They might block it as suspicious.
Here's how to create the Debug File: https://www.hwinfo.com/forum/threads/read-this-before-submitting-a-report.241/
Thanks for the Debug File. Unfortunately it's as I expected and I'm unable to figure out how to access the members.
Is there perhaps any other tool able to show them? CrystalDiskInfo, HD Sentinel..
In that case I'll have to fix this on my side somehow, let me have a look at that...
Update: This will be fixed in the next Beta build and it should work regardless of regional settings or UTF-8 mode.
