I do not know if there is an easier way to do this, so I figured I can ask this as a request (or at least get told how to do it). I have several installers that are integrated with the Windows 7 Toolkit. One of the installers (gfwlivesetup) does not like to be run at the same time as other setups (it gives the error of 'another installer is running'). Is there a way to have these installers run sequentially instead of what appears to be all at the same time?

They already do install sequentially, they install one after another.
