If you are using Windows XP, or if you encountered "Memory protection fault" or "Stack fault" errors while using the MIX programs, you will need patches for each program. This is due to changes in the operating system that require updated Fortran modules.

Please note that the patches are necessary for both DOS and Windows versions of the MIX programs.

Download the XP patches either individually or as a zipped bundle containing all 4 modules.

Save the .EXE files directly to your RRM program directory overwriting the existing files when prompted. There is no need to run these programs to 'install' them; they replace the statistical modules and are used when performing analyses.
