I am running Order of Battle - World War II on my 64 bit Dell computer and often get a purple screen when viewing maps. I have downloaded OOB - US Marines which appears to be 32 bit?
Question: is it just better for me to run all of the OOB in 32 bit as I do on my laptop and don't get any problems?

With OOB I have loaded the 64 bit updates 521 and 523 and still get errors. Any suggestions?

The issue is not related wit you running the 32bit or the 64bit version of the game.
That sounds more a video card issue.
