The db.ini looks fine as is.
Try register the ocx by removing the /s at the end and see if anything fails.
regsvr32 a.ocx
regsvr32 DXAnimatedGIF.ocx
regsvr32 imagelist.ocx
regsvr32 MSCOMCTL.OCX
also, I looked in the program code, and that error comes from 2 possibilities.
One is this sql fails
Code:
SELECT value FROM variables WHERE varname='DBVersion'
or a.ocx fails to register
