Are you talking about Divine Divinity? There are no 'font' files in Beyond Divinity...
Someone else ran into this error because the font folder did not exist ('
..\Divine Divinity\Run\fonts'). They extracted this folder from the CD (see the manual install procedure in the link below). A clean re-install should also fixed that;
Un-install, re-boot, shut down all non essential programs (especially anti-virus), re-install the game. Check if the game starts, then install the patch, re-boot, shut down all non essential programs, start the game again. This procedure is a bit over-cautious, but the best way to avoid install problems.
