MPI File Complications

Common Problems Opening MPI Files

InstallJammer is Not Installed

You encounter an error message such as "%%os%% Can't Open MPI Files" when trying to open your MPI. When this happens, it is commonly due to InstallJammer missing in %%os%%. This will prevent you from double-clicking to open the MPI file because the OS doesn’t know how to handle it.

Tip: When another MPI application is installed, you can choose to open it by selecting "Show Apps" and using that program.

InstallJammer is Out-of-Date

In some cases, you might have a newer (or older) version of a InstallJammer Project File file that is unsupported by your installed application version. If you've got the wrong version of InstallJammer installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: If you right-click on your MPI file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Regardless, most of the MPI file opening problems relate to not having the right version of InstallJammer installed.
