Do I really have to launch the launcher from the MS Store webpage every time I want to play?

Pretty much what the title says, I'm getting an error whenever I try to boot up the launcher from the install folder. The only way I've been able to get into the game is via the MS Store webpage. The error states "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

i use the windows key then click on the pso2 icon

Thanks, Cowmoon. That worked.
