Question about installing MDAC

[Guest]

Hello,
I have a VB6, Excel/Word VBA commercial app for which I need to install MDAC
before installing my app if not present. I use my Wise Installation System
Version 9 to install my app and MDAC 2.6 SP1. One prospect has an old Win 98
Office 97 configuration and I wonder if there are any potential problems or
issues installing this newer MDAC on an older system like that. Per a MS KB
article, it will work, but I'm wondering if it will create any problems with
his other current apps,etc.
Thanks, God bless
Van

Van:

Somewhere around MDAC version 2.5, parts of the MS Jet Engine were
removed as the Jet Engine became a stand-alone structure. You will probably
find that upgrading to later versions of MDAC will definitely cause your
older user to have problems, but a lot of that depends on how sophisticated
your code is. My problems came into play with MS Access VBA but I'd have a
hunch that similar issues will appear with Excel. Also note that going
backwards from a newer MDAC to an older version, while supposedly do-able, is
difficult as MDAC is embedded in a lot of places throughout the MS Windows
environment. Use caution.
