The error message is a system error message: "The application was unable to start correctly".
It happens right after meta injector says it is counting files.
I get the same error after uninstalling all of the mods and reinstalling them. It doesn't look like there are anything special for the meta injector installation...drag files to paz and run rootkit.
So I am suspecting meta injector is no longer supported :C
make sure to have files in the 'files_to_patch' folder or it wont do anthing, if you need files, you need to use the mod installer itself, also make sure you install the modder tool (BDOToolkit) to allow modding (this is not always needed but its just in case).
If you do have this and its not working, try reinstaling the game completely, also delete everything that the uninstall doesn't. Download, allow it to patch, play the game (to make sure its patched and able to launch) exit out and then start with getting the mod tool then after that inject the mod into the files.
Long process but should allow the inject to work again... at least it should on a new install of the game, If sstill not working even after alll that, the injector might need backward compatibility to use as might not be able to be use on windows 11 yet.
