My Issue:
I have created two merge modules. Lets call them A and B. Merge Module B is dependent on A. A installs aaa.dll to windows side-by-side. B contains bbb.dll which registers during installation and is dependent on aaa.dll. As a side note merge module A was created in Install shield 2012 and merge module B was create using the visual studio 2010 wizard.I have created two merge modules. L
