Application Permissions without lowering Security?

As long as you install as an admin and store your media in a location that your UserName has full access to, it should work, The location of the database, if not in default location under the application folder, also needs to be accessible.

I've been using Media monkey for at least ten years - probably nearer fifteen and have never been asked for permissions, and my system is very secure.

what I would suggest is that you right click on the location of your media, and ensure that your UserName has full control of these folders, also locate the database for MM and either move it to an area that you have full access to or use the security tab to add the correct permissions to the folder

Assuming you have the standard dual token set-up, it should just be a case of right clicking on the installer and selecting "Run/install as Admin" which will install the software to it's correct location, and also set the required permissions for access.

The reason to use the user rather than the hidden admin is you need the permissions to relate to your user, The hidden admin already has full access to everywhere so would not need to increase it's permissions.

I personally only use the hidden administrator in an emergency. I also keep two regular admin accounts so that should I ever lock myself out, or my ID corrupts, I can use the secondary admin to sort things or enable the hidden admin, which is always disabled
