Wix Burn: Setting Engine LocalSource() to extract Burn contents

Question

I only guess that the following would set sLocalSourcePath where Payloads would be deployed and would be executed further by Burn instead of doing that in some Temp folder.

Engine.SetLocalSource(sPackageId, sPayloadId, sLocalSourcePath)

If yes, then under which event, should it be called?

Answer 1

SetLocalSource lets the Bootstrapper Application tell the engine where it can find the source of a specific payload or package.

It is not possible for a BA to modify the location of the package cache. There is a feature request open that would allow the user to relocate it (which would apply to all bundles).
