[wix-users] Can two CA's be run at the same time?

Thanks for the reply Kashif, but I think you missed the intent of my question.

I realize that there's a Return="async*" to force asynchronous execution, but I was thinking more of the actions marked Execute="firstSequence" or Execute="deferred".  Since they may be "scheduled" in the InstallUISequence and/or InstallExecuteSequence at the same point, are these ever run asynchronously?  (I felt that the Execute="immediate" actions are safely synchronous.)

The point is: unless I specifically use the Return="async*", can I be assured that no more than one of my CA entries is running at any given time?

Thanks again for the help.

Yes, try asynchronous CA
