Folder Permissions - Can't Change Them

[snpower 16]

I have a new Windows 10 install, and also a new P3D build. Hi Fi Active Sky has alerted me that it can't monitor ambient conditions and needs access to my (x86) folder. I went to that location and attempted to change permissions - and I can't. I also tried other, non P3D folders with the same result. Odd? I seem to have been able to change permissions readily before - this is an administrator account. I could use some insight. Again, new Windows 10 build - I just did a re-install to (ironically) sort out some issues with P3D!!
