Do you have runtime in the data execution prevention list? The post below refers to configurator, but applies to runtime as well.

Also, does your project crash on other machines, or just one? My machine hates PAC display (9.4 in particular) and crashes all the time, but I run it on other machines without issues.
Anyways, I would send an e-mail to support so they can investigate as well - if they find a fix, that helps everyone out.
I also make a copy of the project and start removing things like alarms/super trends/historical logs and then display windows until it doesn’t crash anymore, then I kind of know what area is causing it and that will help support figure it out. Also, see if there is a difference if you start runtime from configurator vs loading runtime direct.
Good luck, be patient and stay on top of support until you get a fix - they like that
