[wix-users] Progress Update Between Two Burn Instances

[Huy Doan]

Hello, I'm implementing the roll back support for my burn boostrapper. The scenario is the old bootstrapper (version 1.0) is already installed. The new bootstrapper (version 2.0) will be launched and perform an upgrade. If something wrong happens during the upgrading process, beside the new bootstrapper automatically rolling back, I will launch the old bootstrapper silently in repair mode. This makes the system stable.

The question is that how can I send the progress of the repair from the old boostrapper to the new bootstrapper so that the new one can display the progress to the user instead of giving them the feeling that the system hangs.

Theoretically, I think of creating a communication pipe between the two processes. However, I don't know how to. I know that Burn has its own internal pipe. I wonder if I can utilize that. I would like to hear some suggestions how to achieve this goal.
