1 - Your load requirements indicate 53MEG and mine indicates 37MEG - Is the install size changed ?
I am testing the installer for the next release.
2 - Your version is V2.42 and mine is V2.46
I didn't update NSIS so far... but that doesn't matter.
I did not see the Drop down Help Files as I see in your version.
Enlarge the "contrib plugin" section, i.e. click on the "plus".
The question for me is, how do we make the users (including you) aware at installation time that not all components are selected in the default install. For me writing this installer this was clearly indicated by the missing checks in the check-boxes and the greyed check-boxes which is a common standard on Windows in nearly
every settings dialog. But even additionally presenting the written text and explicitly stating there that you can/have to choose seems not enough.
The only thing I can think of is presenting a message box whenever you start the installer saying: "Please read whats written and hit the plus sign.". But this seems really weird to me.
