I need my installer to install two different source files (compiled for 32 XOR 64 bit Windows OS) into the same target file. The selection of the source files happens automatically via conditions so that they are mutual exclusive.
With the default packager, this is no problem. With the MultiVolumePackager and neither of the packages selected, this is also no problem.
If one of the packages is selected, the MultiVolumePackager aborts with "Unexpected end of stream - installer corrupt?".
