Can not control permissions in C:/Program Files
I am trying to install a plugin for Matlab, which is installed in C:/Program Files. I have done it on PCs running all OSs many times. A dialogue says I do not have permission. I go to the folder Program Files, right click, properties, security, advanced, click change permissions, and suddenly I just have add, remove, view, enable inheritance buttons, all grayed out. I have read a dozen threads on windows community, and at some point their steps diverge from what I see and I'm stuck.
If I click Change at the top by "trusted installer" I get a dialogue box where I do not know what to do.
Any advice would be appreciated. Windows 10 workstation, I am the only user and administrator.
Thanks
Jim
