If you are using Windows XP, or if you have had problems with "Memory protection fault" or "Stack fault" errors, you will need patches for each MIX program. This is because there have been changes in the operating system which require updated Fortran modules.

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

You may get the XP patches on the Downloads page. They can be downloaded individually or as a zipped bundle containing all 4 modules.

The XP patches replace your existing statistical modules. They must be saved to your RRM program directory overwriting the existing files. You do not need to 'install' or run them as they will be called directly when performing analyses.
