TC.52a configuration options bug? Win10 bug?

[SquareState]

I installed a 64-bit version on my new computer which is Win10, copied the wincmd.key from my old drive and thought things were fine. However, when I try to make any changes to the Options (e.g., Display Hidden Files and System Files, I get "Error: cannot write to c:/program files/totalcmd/wincmd.ini! Please remove the write protection."

But when I check the file attributes for wincmd.ini, it is not read-only.

This is a single user system and I have administrator rights. Is there something I have to do to assert administrator status?

Probably you have not rights to write into c:/program files/totalcmd directory?

It not a bug.
You just seem to not fully understand the security of your new OS
Even as Administrator you cant write by default into Program files tree.
To fix it use the installer which will normaly place the ini files into your user tree.
