I've created a custom launcher for RocketLauncher thus:
executable = F:/RocketLauncher/RocketLauncher.exe
arguments = "%ITEM_COLLECTION_NAME%" "%ITEM_NAME%"
However, when I try to launch it nothing happens. A look at the log suggests that the variables are working correctly and indeed the same command works fine from the command line, just not from RetroFE.

Am I missing something?
