Ironically an old school AMD Radeon HD 6600 series card here with an equally old school AMD 6130 quad core Processor. Just odd that the plugins tab loads fine, but addons does not. I wonder if it's something with not accessing addons.xml properly.
I tried disabling Win firewall and loading, no change.
I tried disabling avast and loading, no change.
Edit: tried lowering UAC all the way down and rebooting, still no luck.
Either way, I have no problem loading them up "manually," but I'd sure prefer being able to do that in a file that then runs each time!
@ Megabaito, how do I run using integrated card? When I right click, the only run option I see is as administrator.
Double edit: I should note, when I installed Windower, the addons folder was empty, I had to manually download all of the addons from github and put them in the folder so I could load them via the ingame command.
