Once resolved, adopt these best practices:

Moldflow is RAM-hungry. A 3D mesh of 2 million tetrahedral elements can easily require 16-32 GB of RAM. If your physical RAM is full, Windows uses a page file on the SSD/HDD. If the page file is too small or the drive is full, Windows denies memory allocation requests. The Moldflow solver, unable to allocate memory, crashes with Error 99998.

If the error persists after the basic steps, use these advanced techniques.
