I couldn't find much, but maybe it'll point you in the right direction.
I'm by no means any expert, but here's how I understand it.
The installshield wizard (what's installing the game) is trying to use a faulty or already in use dll. It wasn't able to find it, or use it, or whatever. I don't understand myself as I'm not much of a programmer, but that's what I gather.
The few sites I've found with solutions suggest:
Make sure that only one instance of the application is running at a time.
Turn off all superfluous programs running in the background (at least for the install) such as anti-virus, instant messengers, etc... before trying to install the game.
Delete the install directory, reboot, and try again. Duh, right?
I'm sure you've done this.
If there are two CD_Roms available, try to install from both.
If all else fails, a fellow with a similar problem concerning Battlefield 1942, boot up in safe mode and install.
