Hello,when installing an airline PAI package with the installer I get an Error Message called Error120 "TTols is unable to identify your FS Version"Some weeks ago everything worked fine with the installation of AI packages but now i get this message.Any ideas what to do? I already contacted PAI but waiting for an answer can be take some days :-(many thanks

That sounds odd...What airline package (if it is a specific one)? Have you tried multiple packages?

Probably ttools can't find fs because your registry path has been messed up:http://www.flight1software.com/files/FS_Registry_Repair.exeregards,Mark

thanks for your help but it is still not working :-(
