how can I invoke another msi packet in one msi custom action?

Can anybody tell me how can I invoke another msi packet in one msi custom actio开发者_如何学Pythonn with wix?

You can't; MSI doesn't support running multiple install transactions simultaneously. You need to use an external program (bootstrapper/chainer) to install the packages in a chain.

Yes, you need to use a bootstrapper for the job. I have been denying this fact for an extended period of time (thinking "what!? this supposedly advanced thingie can't even do this?) and I finally accepted it.
