Grigore,

Nothing is simple under Windows. :)

I don't see why you've to do it the hard way but if you feel like tracking down what has been updated by the install, download RegMon and FileMon from http://www.sysinternals.com/ntw2k/utilities.shtml.

Somehow, I have the feeling I only have to write 2-3 keys in registry, nothing more. Something makes Windows to show the driver in that ODBC data sources window. If I could make the same, then I'm done.
