doveman 7 Posted November 9, 2015 So both my Win8.1 and Win10 installs point to the same folder for My Documents (F:\Data\Main\My Documents) which has the "Arma 3" and "Arma 3 - Other profiles" folders under it. I haven't used Win10 much yet and I don't think I've tried to run ArmA 3 under it before yesterday. Anyway, it worked initially but the next time I tried, the Arma3.exe process launched but that's it, no splashscreen or anything even after waiting much longer than normal. I saw the BE process as well sometimes. I was using PwS to launch but then tried with the official launcher (after clicking Play in Steam) and even with a batch file I've created for starting it with my mods for emergencies. Then I rebooted back to Win8.1 and had the same problem there. It's been working fine under that so it must be something that Win10 did that broke it. In the end, I found that I had to rename the My Documents\Arma 3 folder (to Arma 3.bak) and launch it with the official launcher, which created a new folder and Arma3.cfg file. I tried launching with my batch file but that didn't work until after I'd launched with the official launcher once. I then copied the backed-up files (from \Arma 3.bak to \Arma 3 and it still worked, so the files were obviously not corrupted. I only really needed to copy the Arma3.cfg, as the profile I use is in "Arma 3 - Other profiles" and the two profiles in "Arma 3" are just redundant ones created automatically and named after my Windows usernames. So what could be causing this problem? I obviously don't want to have to keep recreating this folder every time I switch between Windows. I haven't actually tried running A3 under Win10 again yet but I'm pretty sure that's what I'll have to do until I find the proper solution. When I was trying to get A3 working under Win10, I tried turning UAC off (bottom of slider) in Win10 but then A3 wouldn't load at all, even if I set arma3.exe to run as administrator in it's properties, so I had to turn UAC up a notch and then it prompted me to allow A3 to run. In Win8.1 I actually have UAC completely disabled using this registry tweak http://www.eightforums.com/system-security/2434-disable-uac-completely.html Apparently that breaks the Start Menu in Windows 10 though! I haven't tried this method yet http://www.ghacks.net/2015/08/22/make-uac-prompts-less-intrusive-on-windows-10/ Share this post Link to post Share on other sites
