Hi Bill,
I was having problems installing the DBI controls on my new machine. I'm running NT 4.0 with SP4 on an HP Vetra pentium III 633 with 128 mb ram. Everything I tried to do to register the DBI control failed in an error.
DBI support was no help. I receive on message from them tell me to load the MFC42 file again. Well to make a long story short I use an installation program called install maker by clickteam. I simply added all the DBI controls to an installation exe and told it to install the control in the system folder and register them. Also to increment the dll count. It worked like a champ.
Hope this can help you.
