When you say reinstall All .NET frameworks do you mean to download 1 2 3 and 4? and install them in order? (sorry I don't really understand what you meant)
Also Where do i get the Visual C++ library? Also the error i got from debugging had nothing to do with the initialize problem the problem i got was a problem in the code where i had to type the - MW3.Hack("iw5mp") and MW3.SetInt(%H1cd8c54, TextBox1.Text) i tried to run it, and it said there was an error with them i think it was something like Mw3.Hack is not a valid window forms application
If you search up (on youtube) "mick2021" i followed his tutorial on youtube
