I want to only install MDAC2.5 on NT4 box but MDAC2.6 on a W2K box.  If I use MDAC merge modules provided by InstallShield, how can I modify these merge modules to do the conditional installs?

When I opened the MDAC26.MSM file as an ISWI project, I
found that there are custom actions in the ModuleInstallUISequence and the
ModuleInstallExecuteSequence tables which are then merged with the InstallUISequence and InstallExecuteSequence tables, respectively.  How can I change the conditions in these tables to only drop a mdac2.5 on NT4 but MDAC2.6 on w2k?  Also can I modify the condition to suppress the reboot from MDAC?

Many thanks in advance!

Merge modules are not really designed to have the complete merge module not installed.
What they do allow is to conditionally set the components to install on a certain condition, or alternatively the feature for the MM to no install.

I would reccommend emailing install shield and ask them if you can add in conditions for the components that they supply in their MM.

You could add a condition like
VersionNT<500
on the custom action that installs MDAC 2.5, etc.
