Yes I also got the message incompatible with windows 10. I just closed out that window and kept going like I didn't see it. I made sure that nothing was updated before I installed Fallout 3, Fomm. I found out that like Win XP that Win 10 also uses a lot of memory and that 4 gb is not enough to run the game with any mods. But Like I did in Win XP I went to the Task Manage and started to turn off things in my user section that I didnot need. In return my game speeded up and I played for several years on a Win XP Pro machine with 4 gb. Yes I know that Win XP Pro does not show 4 gb but only 3. something. Back to win 10. I installed Fallout3 in a Folder named Games outside of the Win10 Programs and X86 Folders. I laso installed the old Fomm into the same Directory that all the folders are in. ie. Games, Program Files,Program Files (X86) in the C:/ Directory.I installed another version of FOMM but it didn't work so I download the old Fomm and installed it.After installing Fomm I went into the C:/GeMM/data/ folder and copied the xlive.dll form that folder and pasted it into theC:\Games\Bethesda Softworks\Fallout 3? folder. Then I open the Fose Folder and copied everything and pasted it into Fallout3 Folder. I started to look around and found the Nexus Mod Manager and Downloaded it. When I would download a Mod with it I found that sometimes that afer I finished downloading a Mod and tried to run it , it would tell me that the whole mod was not there, But I like the way that it unloaded itself when I clicked on run Fose and that was more memory for my game. If you can get your game to work without Fomm, Fose or any Mods then I think that it has something to do with your configuration. If Your game works then your halfway there. Right now I am playing with 135 mods on Win10 with 4 gb Ram. I install my Mods with Fomm and vaidate it and trun off Fomm and then Run Nexus Mod Manager. No I do not download or install any Mods with Nexus Mod Manager. It works for me I hope that this helps someone. And NO I am Not an xpert only a player and I love this Game... It's the only Game I play and have played for many years, always something new. Thanks to the people Who made this Game and those that made the Mods I use and also to the people at Nexus that hosted and brought all these great Mods to one place. I just wish that all the Mods from times past were still on here. Jinn
