      DirkRockface No. I can verify that black ops was not selected. Same error. no reason for that error.

                  I can confirm i'm also now unable to launch MW3 since the steam executable update 😞 their file is about 15gb for me as opposed to 6mb ? hopefully the mods make a workaround

                    ohfrankyboy i am also having the same issue as well, whenever i go to the MW3 folder not in the plutonium client it shows a bunch of stuff like the exe and all that. but when i go to locate the directory it shows just the two folders that you have in the screenshot and then fails to launch.

                        el_chapo710 that folder selection window only shows folders, that's why you don't see the extra files in that view (they are there, they are just hidden to help you find the folder)

                        Your issue is that MW3 got an update and it is not compatible with plutonium. so your game files probably auto updated and now you can't play. I think there are a few ways to downgrade (posted in the plutonium discord).

                          ohfrankyboy well, as you can see in the picture you posted:

                          aeac79e0-6ebd-4d67-a3bc-bc97b2eb0fa9-image.jpeg

                          plutonium is LOOKING in the Call of Duty Black Ops folder... so i don't know what to tell you!

                          BUT if your game was auto updated, then the new version won't work with plutonium and you'll need to get the old version.

                            There was a call Of Duty Modern Warfare 3 giant update and it deleted a bunch of important files or changed the .exe and other files I need for the Plutonium mod to work, thankfully I can still play MW2, WAW and BO2 (But I had to update the entire IW4X using the IW4X launcher and that overwrote files but MW3, isnt working.
                            Error files and file problems 'AIL_set_redist_directory@4 from module 'mss32.dll'

                            Possibly that mss32.dll needs updating perhaps.

                                    hopefully this gets fixed soon, i enjoy playing iw5 on plutonium, but its not so amazing that i'll go thru the trouble of downgrading.
