This is something that I generally forget whenever I create a new dev-box. Visual Studio needs to be running as Administrator otherwise you’ll get messages such as “Access to the path ‘K:\AosService\PackagesLocalDirectory\Bin\InstalledVersion.json’ is denied”: and “Visual Studio is not running as administrator. Finance and Operations (Dynamics 365) requires Visual Studio to be running as administrator. Please restart Visual Studio as administrator”: You can always right-click on your VS-shortcut and select “Run as administrator”, but if you’re even remotely like me, you’ll forget that approx 82% of the times. So what you need to do is to modify the shortcut you’re using. In my case I modify the shortcut in my Taskbar. Right click on the shortcut for Visual Studio and instead of clicking “Run as administrator” you click Properties: In the properties window you click the Advanced button: In the window that opens up tick the “Run as administrator”: Click OK and OK and you’re done. Next time you use the shortcut it runs VS as administrator.
