Bruel & Kjaer's Predictor software running on Windows 10 loses license files

We have a few machines on Windows 10 that inexplicably lose the 5-8 license files that inform Predictor that is it a legit copy (along with a USB dongle). It won't recognize the dongle without the license files in place. They are simply disappearing from these machines. They are not quarantined by the AV software nor are they found in the recycle bin on the affected machines.

Any chance the dongle or the software is not Windows 10 compliant?  That would cause your issue.

Unknown. They are so ridiculously expensive - $10-15K!!! - that we can't just replace them. B&K is a very pricey niche product. They haven't answered my support question either - I think they acquired the software publisher and it they who do the actual support. But thank you for that thought. That may indeed be the case. At least it's a direction we can pursue.
We run B&K software with dongles (for 10 years, maybe) - never seen that, although we use win10 for over a year now.
If the dongle were defective, the files wouldn't vanish - sorry, there's no connection between file deletions and a dongle.

You can setup NTFS auditing to monitor who/what process deletes those files. Do you know how?
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Windows 10 does not delete files on its own. However McKnife's suggestion sounds like a good one

Can you try uninstalling the software, restarting and then installing it again.

If all else fails...
Restore license files and deny delete/modify rights to Everyone

I just heard back from someone at B&K who had reported this to the original publisher, Softnoise, who had this to say...

"We do have 1 customer who experienced the same effect. We suggested to first save the license files on the desktop, so not in the program folder. And then copy the license files from the desktop to the program folder. The customer was not sure if he followed this advice exactly but suddenly it worked again. He did remember to try some alternative ways to install the license files."

We currently copy them down form a server share that houses our software repository so I'm not sure why it would work this way as opposed to where we copy them from.

We have a few machines on Windows 10 ...  I'm not sure why it would work this way as opposed to where we copy them from.

That is because the Windows 10 Program Folder is much more secure than earlier systems. The license file should not really be in there but that may be why it is getting deleted.

Saving to a neutral location and then copying to the Program Folder will trigger UAC and a permission prompt. Once copied, it should stick.   I have done this with Comm View (tamosoft)
