Please add "Manage installation logging" to non-MSI installers when available. Although there are exceptions with badly built/scripted packages, most installers support setting a log path via command line switch and the programs installer builder programs log switches, as well as program packages are well documented. InstallShield: /f2%logpath%, Inno: /LOG="%logpath%", etc.
This is already implemented. When we know of the logging switch for EXE based application we will support enabling it.
