So MadFlac is installed to Program Files (x86), I then double clicked the install.bat file, same error, I then dragged and dropped the madFlac.ax file onto InstallFilter.exe and got the same error. Tried other Flacs and got the same error thinking I had a corrupt file but that doesn't seem to be the case. Uninstalled reinstalled MadFlac and ImgBurn. Not sure what else to do.
