Nofux To be able to run Cosmoteer you need to be Administrator on your computer, you must be on the that user account. If you're running Windows 10 this is how to check if you're running it.
Click on the Start button, the Start Menu will pop up.
Right-click the name (or icon, depending on the version Windows 10) of the current account, located at the top left part of the Start Menu, then click on Change account settings.
The Settings window will pop up and under the name of the account if you see the word "Administrator" then it is an Administrator account.
Kind regards
