You do not have permissions to mount and modify this image

I keep getting this when clicking "Mount WIM" and for the life of me I can't figure out why. I'm moving heaven and earth trying to add a folder to a WIM file and all the solutions are too difficult so far.
I have full permissions to the WIM file as far as I know...I would not know how to give myself anymore permission than I have.
The file is named INSTALL.WIM and is part of Windows 7 (Thin PC) distro. I extracted the ISO to a folder and have full permission to the INSTALL.WIM file. Your app doesn't provide a Read/Write option and the Read Only box is unchecked.
What am I missing?

Error: 0xc1510111

You do not have permissions to mount and modify this image.
Verify that you have Read/Write permissions or mount the image using the /ReadOnly option. Note that you cannot commit changes to an image with read-only permissions.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

Please ignore. Pesky Controlled Folder Access in Windows 10 was causing this. Turned it off and it mounted and allowed me to do everything I needed.
