wyUpdate command line return values

(Moved to its own thread)

I'm having trouble getting wyUpdate commandline switches working as expected.

I have v1.0.4 of my application installed on my test machine, and v1.0.5 ready to go on my update server. Running wyUpdate.exe pops up the update dialog as expected.But wyUpdate /quickcheck /justcheck /outputinfo shows nothing (nothing written to stdout). /outputinfo without a filename doesn't seem to do anything, contrary to the documentation.With /outputinfo=wy.txt, wy.txt contains the version and release notes as expected.

And I have been completely unable to get wyUpdate to return the expected 2 with any combination of /quickcheck /justcheck /noerr - or rather, I suspect I must be reading it wrong.

(At this stage I'm just running it from cmd, and checking %errorlevel% for the result - though I'm doing this in the first place because I wasn't seeing the results I expected when running it from Process.Start() ).

What am I doing wrong?
