I have the Aerosoft Box version 1.20 with B747-8 download ! Win 7 64bit best regradsChris

It is probably a security issue, assign admin rights to the pmdg folder and subfolders. Also might try it when running MSFS 'as admin.'

I have installed new and run FSX as admin mode! I have new installed as admin nothing . I hope a admin can me tell me somewone more?! Same useres on Aerosoft forum have the same problem i think its a bug of Win7 64bit. Thanksbest regrads
