Desperate problem re-installing

[JohnYorkUK 3]

Have recently upgraded my system from Vista 32bit to Windows 7 64bit.I use this system almost solely for Flight Sim. I have reinstalled all my sceneries and aircraft without problem ...However, when I try to install PMDG 747 (CD version) I get 'Emulator detected ! Please deactivate virtual drive and emulation software'I am not aware I have any emulation or virtual drive ? I maybe wrong, I'm not computer-literate really. However when I click on 'Device and Printers', I see something called 'Beanbag Emulation Device' which I havent a clue about. Anyway, please help. I've contacted PMDG who said I should email Aerosoft as mine is an original CD copy yet their suggestions and attempts at helping me have proved fruitless.After a week of tearing my hair out over this, I'm desperate to get back in the air, can anyone help please ? I have the download of the new 8i but I can't do anything with it because of my orginal 747X CD problem. I don't know what else to do.Thank youJohnI should add I used a Seagate 1Tb external drive and Microsoft Easy Transfer to back up data before i installed Windows 7, I don't know if that is a factor ? Have not copied any files back from it though. I'm not very computer literate, sorry. I just fly.John
