The problem is the install is in 32 bit and the function I need to call can only be called from a 64bit process (if 64 bit OS). I need the 64bit helper exe in my msi to be extracted to run it. (my app has a dll that may be loaded in another process at time of upgrade. this "unlocker" exe removes it)
1. is there a way to run the copy files twice? once to copy all that can be copied, run the unlocker and then copy again? 2. or Johns suggestion of streaming the exe out...how would I go about that? 3. or could a separate <copyfile> element work at all?
