This problem affects Visual Studio 2003 projects that have been updated to Visual Studio 2005 or great. If your solution has a Setup Project that depends on old merge modules, you might get the following error when trying to build the Setup Project.
Unable to find module file 'C:\Program Files\Common Files\Merge Modules\Crystal_Database_Access2003.msm'
Basically, the merge modules no longer exist in the given location. Fixing the problem is as easy as copying the missing modules into the ‘C:\Program Files\Common Files\Merge Modules\’folder, but tracking down the files was a bit harder than it should have been.
You can download the merge modules you need from the following address. Hope this helps.
