Never ever install games in the Program Files, a good practice is to make a separate partition for things you care about and consider the C drive expendable.The reason why is probably permissions, Program Files folders behave totally strange and differently on a modern Windows system, only good fix is to have FSX somewhere else.Heck, even just C:\FSX is good enough.

I am having simular problems With a the laptop Windows 2003, FSX Gold and the admin privileges set to Power User administrative privileges, and it is causing the software to not operate as needed.There are various Error screens that appear sequentially when trying to initiate PMDG 747-400 software. Here are some of the screen messages;- PMDG_747400_Main.DLL cannot find PMDGOptions.DLL- PMDG_747400_ACS.DLL cannot find PMDGOptions.DLL- PMDG_747400_OVERHEAD.DLL cannot find PMDGOptions.DLLDo I require full Admin rights on the computer it is installed?
