When I run FS, I get a CTD whilst the initial splash screen is showing. This started happening after I downloaded Cloud9 (now on FSDT's) Amsterdam scenery, from the FSDT website. This installs several bglman files in the Modules folder. The problem, and what is causing the CTD, is that there is one copy of the file Esellerateengine.dll in the (hidden) folder C:\ProgramData\Esellerate, which is as it should be for Windows 7, but every time I run FS9, a second copy of the file installs into the C:\Windows folder (which was correct for Windows XP, I think). Having the latter file there causes FS to CTD. I remove the latter file and FS starts fine this time, but installs the dll file in Windows again. Can anyone say why? I do not have the sim running in XP Compatibility Mode so am at a loss to say why this is happening.When I uninstall the Amsterdam scenery, I still have two dll files, but no CTD as the bglman files are no longer present in the Modules folder. OK, but this means I can't install that scenery. I have a thread at the FSDT site, but I thought I'd post this here as someone may be able to help with why FS9 is installing a copy of the dll in the main Windows folder when I am running Windows 7 (PC came with it, not an upgrade from XP). As a last resort I could write a script that deletes the dll file from Windows when FS9 finishes loading, but that's only a 'sticking plaster job' - I'd like to get to the bottom of things if possible and stop the file being created in the first place.Thank you,Martin

.. I think it's a case of locating other programmes that install eSellerateEngine.dll - I've been Googling this but not much luck so far. FSDT suggest FS_Earth - I'll test that as soon as I can. Other suggestions?

Just in case anyone else has this problem, it was the fs_earth.dll in my FS9/Modules folder that was causing the problem. Maybe I have an old version ...M.

M-I've just started to have the same problem with FS9 in Windows 7. I have not installed any new scenery. However, I did try and install some software that would convert my Sony Handycam into a webcam. Problem seemed to have started after that. I've removed the program, cleaned the registry, and tried a backup copy of the FS9.cfg, but perhaps there is still some trace of the rogue software somewhere that is causing FS9 to CTD. Any ideas?Regards,
