Try a different optical drive, if possible. Some optical drives can have problems with some CDs, and if there is a defect or non-visible physical damage with the CD, some optical drives are better than others at trying to correct for that.

Did your father try manually extracting the '..\disc2\wizm.rar' file into the to '..\Divine Divinity\Run' folder, as described in the manual install procedure? If that still gives a CRC error, try copying the rar file to the hard drive, and see if Winrar will extract it from there, or if it can fix the archive and then extract the files.

The error with the loading screen is not directly related to the male wizard problem, since the relevant tga image files are on the play CD.
To fix this, select the 'disc3\static' folder on the play CD, and copy the 5 *.tga files into the '..\Divine Divinity\Run\static' folder on the hard drive. The 5 *.bik files are not required (they would just take up an extra 76MB of hard drive space if copied) and it sounds like the objects.000 file was installed correctly. After copying the files, select the '..\run\static' folder on the hard drive, and clear the read-only attribute.


If you can't install it properly from a different drive, have your father try a manual installation and then re-install the patch (some re-release versions of the game may already be updated to the latest 1.0034A version, as shown in the bottom right corner of the main menu, so would not need to be patched).
