hlminx 301 Posted November 4, 2018 Report Share Posted November 4, 2018 Hiya SInce moving across to FSX Steam, I am starting to find software that just will not play nicely with Steam Edition.. Has anyone with FSX:SE and UT2 come across this error as soon as they launch it? Program Error Error loading aircraft assignments Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified I have tried uninstalling and reinstalling without luck. I have .NET version 4.7.2 so I'm well up to date on that version. I have spent hours looking on the internet and on this site for the same issue, but only came across slightly different error message, or in some cases, the same question, but no answer.. Judging by the lack of responses on the Flight 1/UT2 site, i'll be drawing my pension before I get a reply! Anyone got any ideas?? Cheers Steph Link to post Share on other sites
mutley 4,498 Posted November 4, 2018 Report Share Posted November 4, 2018 I think it is looking for .Net 3.5, try installing/updating from here https://www.microsoft.com/en-us/download/details.aspx?id=22 Link to post Share on other sites
hlminx 301 Posted November 4, 2018 Author Report Share Posted November 4, 2018 Hi Joe Thanks for the speedy reply. Funnily enough, i'd tried to download 3.5 a week ago but was unable to re-set the Windows Features page to allow it to install.. Not sure what happened, but I just tried it again today, and for some reason, it allowed me to change the settings and UT2 now works! For the benefit of anyone else that gets this problem in future, this is what I did to fix the error message: From the Windows Control Panel, select the Programs and Features, then Turn Windows Features on or off My Microsoft .NET Framework 3.5.1 was not ticked. I clicked the + to open the options and ticked both. Re-launching UT2 I no longer get the error. Link to post Share on other sites

dodgy-alan 1,587 Posted November 4, 2018 Report Share Posted November 4, 2018 I'm still running FSX-A and given the small amount of time I spend on the sim at times I cannot see me upgrading anytime soon. Hell it took me several years to change from FS9 ! LOL Link to post Share on other sites
