This is a very good question and one that I think needs to be answered by Crystal Decisions. They will need to provide a msm update or you will need to manually perform this update on each client after you install the original DLL. Not a good alternative.

>ok, the crystaldecisions.windows.forms.dll is not getting updated in the installation. if i try to add it to my installation project, .NET says it is already there, because it is included the merge module managed.msm. How does merge modules work or what do I need to do to get this dll to update on the machines i currently have the application installed on and the machines that I will install on later. thanks.
