If you’ve recently installed OBS but can’t launch it and experiencing the error, “Procedure entry point IsWow64Process2 could not be located in the dynamic link library…” as pictured below, I have a quick fix for you.
Simply download the OBS files contained in the link below. Extract the files and .rar archive and replace the OBS files with those in your installation folder. Ensure you overwrite existing files.
That should fix your issue.
If that didn’t fix your problem, sorry mate! I tried my best. Maybe try Streamlabs OBS.
