Tracking down program crashes from DLL issues is very tricky. There is a Microsoft tool called "procmon" that is free to download that will monitor all the low level system calls while it is running. You could run that then try to run Fluent or CFX until it fails then turn off capturing in procmon otherwise it will keep on logging system calls. You can look in the process tree and filter on just the tree items for Fluent/CFX and see what DLLls they have loaded. Or maybe search for "system32" to see what DLLs got loaded from system32.
