Re: Can 4.0 SE & 7.1 SE coexist?

This will *not* work as several have allready said. If you for some reason can't upgrade the tools and recompile the application you do however have another option. You can use one of the third party ODBC drivers that does not need or use I-Net. At least the OpenLink drivers does support the SE 4.0 engine on SCO. (See http://www.openlinksw.com) You also get the added benefit of a much better ODBC driver. Read their whitepaper.
