Still not resolved.
Looks like the issue is Visual Studio Crystal Reports extension. My guess is because Epicor is 32 bit. My OS is 64. Visual studio is 64 and so is Crystal Reports extension.
32 bit version of Crystal Reports was installed on my machine and it worked previously. Once I install Visual Studio with the Crystal Reports extension it breaks.
Tried to install all 32 bit but Crystal Reports extension always comes in as 64 bit since the OS is 64 bit.
Seems like the only way to edit Crystal Reports is setup another machine and do the editing on that and testing on my main machine. Tried making this work every way but cannot seem to get it to work.
Looks similar to this… (though this is old)
