I'm trying to uninstall a program called Guitar Pro and I always get an error message that reads: "File D:\Program Files (x86)\Guitar Pro 6\unins000.dat could not be opened. Cannot uninstall. Error 5: Access is denied."

I'm pretty sure it has something to do with administrative authority or having ownership of the folder, but I don't know much about this type of thing. I've searched a few places and still don't have a good idea of what to do. My account on Windows 10 should be the only one on there, and it's supposed to be the admin. I know I probably haven't listed enough information for a quick fix but I don't know where to go from here. Any help is very appreciated!

Solution
Open File Explorer, find the folder/file.

Right click and select Properties. See if you can change the Security settings/ Permissions there in order to uninstall or delete the .dat file.
