Start FileCheck, switch to the Verify tab, click on the '...' button and browse to the appropriate CRC file, then click on the 'Verify' button. Any differences between your install and mine will be listed.
Divine Divinity CRC files (58KB)
FileCheck expects the files to be in the original locations to verify, so if you installed Divinity to a location other than the default (
C:\Program Files\Divine Divinity), open the CRC file in Wordpad (for example), and do a search-and-replace so the file/folder paths match your install.
