I downloaded the CRforVS_mergemodules_13_0_1 zip file, extracted everything.
In Visual Studio 2010, I right-clicked my Setup project, clicked Add, clicked Merge Module. Then I selected all of the msm files that were extracted in the first step above.
The project compiled fine, and my MSI file grew to 79,164 KB (up from about 1/2 MB), but when I installed it on another machine, the Crystal Reports runtime didn't install.
Did I do something wrong?
