Installation on a clean PC with the settings and configs of the old PC

When you install AES on a clean new PC, you can add and assign Credits as normal, but you lose all setting and configs.

The best way is, to save all *.DAT Files you find in the ..\Aerosoft\AES maindir and create a ..\Aerosoft\AES directory on the new PC, copy the files there and then start the newest Installer. The Installer will add all needed program files, but keeps the setting and all Credits and assignments are back. Then you only need to mark all you allready installed addon Airports to "FS9" in the list, then all parts are back there too. In this case, also you Aircraft-Door-Settings (Intelliscene.cfg) should be back, aslong as the Aircraft is installed in the same Subdirectoryname below AIRCRAFT as on the old PC (what should be automatically for all payware aircrafts)

If I copy all the .dat files and run the new installation, will the AES work if I install one of the AES-supported sceneries LATER?

Yes. As long as the Scenery is not installed, this Airport is red in AEShelp, but (if credits was assiged) allready in FULL Mode. When AEShelp detect the scenery after you install it, this Airport goes darkgreen and you can set him aktive (FS9) by a doubleclick of his line. The he is full active again. No need to install all sceneries first.
