"Save data saving failed..." Error, Can't Save on PC

I play SN on an iMac and am enjoying the game tremendously. My father purchased the standalone game for his PC (fully updated Windows 10, laptop is less than 2 years old) from an on-line retailer, i.e., not Steam or Epic. We got the game to load and run by launching in Administrator mode, but when he tries to save a game, he gets the following error in a red SN error dialog:

Save data saving failed (Access to the path "C:/ProgramData/Unknown Worlds/Subnautica\TempSave\tmp171232\CellsCache\baked-batch-cells-9-18-7.bin" or "C\Program Files (x86)\Unknown


I assume that there is more to the message, but that is all that will fit in the dialog box. Note the changing direction of the slashes in the first path. I don't know if that's significant or useful. From what I've read about other users' save problems, my lead suspect is a permissions issue, but I have not had a chance to get back to the PC to investigate that in detail.

I have not seen an example of this specific Save problem in this or any other forum I've searched, though it now occurs to me that if someone was having a Save problem, even if they were using Steam or Epic, I might be able to adapt the solution to the regular Windows file structure that Dad's game is installed in.

Also when I get back in front of the PC, I will try to submit a report through the in-game feedback system, though I'm not sure if it will be able to capture the dialog because I don't know if F8 will be working while the dialog is showing.

Thanks in advance for any help you can provide.

    Update: The in-game feedback system does not work with the dialog open. It may not have been operable at all, but I'm hazy, trying to remember from 5 days ago, and I didn't take notes. That's a whole other bunch of interface features to troubleshoot. Next time I'm on the system, I will try to submit feedback again, just without the dialog visible.
