I have had no problems with FSX until today when I tried to install a whole load of AI airctaft and the AITC Programme.I have uninstalled the lot but still get the dreaded 'Fatal Error' message when I start FSX.I have deleted the traffic.bgl files from WOAI and I think I have removed all WOAI files.I have also ran it as Windows XP and Administrator. I do not like the look of downloading the .dll file mentioned in other forums as that causes issues in other Windows programmes.I do not think I can face uninstalling everything and starting again!Does anyone have any ideas?Windows 7 - 64 Bit // AMD6990 4gb Graphics // 16GB Ram // i7 2600 - OC 4.8ghz

Delete the FSX.cfg, restart FSX and let the config rebuild itself.Also, what was the 'fatal error' message? It should see it in the Event Viewer for the date and time your sim crashed. What module crashed?Best regards,Jim

Hello and thank you for replying.I tried the .cfg solution but it did not solve the issue. However, I took off 'World of AI' and all of my add ons and left FSX on. It started working again and I re-installed my add ons. All is working fine but I have not put 'World of AI' on again.Do you think it was because I tried to put too many airlines on 'World of AI' all at once?Are there any tips on putting 'World of AI' on Windows 7 64bit?

I doubt installing too many airlines would cause the problem. The solution is proper installation. I just read the directions - http://www.world-of-ai.com/installer.html - and one thing that is required is Microsoft .Net. That comes with Windows 7 but you need to make sure Windows update has updated it to the latest. You also should disable any anti-virus and Windows UAC when installing this program. Make sure you have Administrative Rights to install by right clicking the execute and selecting 'Run as Administrator'. Anti-virus programs and UAC are there to protect you from evil people in the world and sometimes they don't allow a registry item to be make or changed during an installation causing all kinds of problems.If you want more suggestions, do what I did and do a Google search for "tips on putting World of AI on Windows 7 64 bit". There are more than a hundred suggestions that you can check out.Best regards,Jim
