Typically, the merge modules listed in DEveloper (I'm assuming that you are using Developer 8.0) based on a setting in the MergeModule tabs in Tools/Options.
Make sure that the MergeModule search path includes the following "C:\Program Files\InstallShield\AdminStudio\5.0\Developer\Objects". If not, add the path and restart Developer.
Then go to the Redistributables view and Access97.msm should be displayed in the Merge Module list. Select the CheckBox for Access97 to include this merge module in the path.
If you have any issues, let me know.
