I can't seem to find where I can add my name or how to edit my post. I guess I should have said installed. I do have the disc for FSX(which I purchased with the product key). So I have FSX boxed version with SP1 and SP2 installed and it still doesn't work.

So I just bought a brand new gaming computer that came with Windowns 10. I downloaded FSX as well as the 2 service packs from microsoft. I didn't have my anti-virus enabled so it wouldn't mess with the downloads. When I try to open a 737 the message,"Warning: the PMDG product was unable to create its work files. Please make sure that you are running Flight Simulator X as administrator." appears. Any ideas why this message is popping up and how do I fix it? Thanks
