Can't Install Fonts in Win10Pro64 Anniversary Edition

Hi...I'll admit it, I need help.

I have an extensive collection of fonts that are totally different from the limited Win10 array. For example: Clearface and Korinna in many weights and styles.

My highly-efficient and wonderful Font Navigator 4.1.0 does not seem to work since I let Win10 install its Anniversary Edition.

I also tried copying *.ttf font files into the c:\windows\fonts folder to no avail, getting this error message: "This file cannot be copied due to an access violation." I have also received: "Access denied."

These same fonts worked perfectly prior to Anniversary Edition.

Unfortunately, I have many, many docs and pubs that use my fonts which are not in the MS set, and I need to update and revise them frequently. This forum has been immensely helpful in the past, and I am hoping that one of the resident gurus can give this non-technie a way out of this perplexing conundrum.

I found a solution. Disregard yesterday's post.
