Installshield LE TFS Build succeeds but does not produce output - visual-studio-2012

Question

I have a solution in Visual Studio 2012 which contains multiple projects - a web application, some class libraries, a couple of database projects and an Installshield LE 2013 project.
If I build the solution for Release, locally, the ISLE project creates and outputs a setup.exe and associated msi etc. However, if I build the solution with Release configuration through TFS 2013 build automation, the build succeeds, produces outputs for all projects and drops them in the drop location with the exception of the ISLE project. No setup.exe and no .msi files are created on the build machine. The tail end of the build log is included below on Detailed mode:
I modified my islproj file to include an AfterGet target as suggested by This Post to avoid the -2200 error described there, and you can see this target in the log in case you are wondering why it's there...
How can I ask the build agent to actually compile my installer?
....omitted other projects build logging....
