In Windows 10 there are three types of users, Administrators, Standard Users, and Modified Standard Users. Administrators can do anything including showing hidden files and their extensions, manage Standard Users and give Standard Users special rights making them Modified Standard Users. A Standard User can install software under their own account and it inherits their security rights as to actions it can accomplish. Administrators installing software gives the software inherited Administrator rights. IMHO all software, including RM should be installed from the Administrator account in case it needs some rights that the Standard User does not have. An alternative is the solution I gave Ladybufrwv, right click the icon and select Run as administrator.
Jerry, you commented about hidden files and file extensions which is easily fixed in Win10. Right Click on the Windows icon in the bottom left of the screen and select Settings. In the search bar type file extensions and it will take you to where you can change the settings. You have to set the radio button to show hidden files and uncheck the box on hide extensions.
