InstallAware

First of all I am new working with IA.
I have released Version 11 and now I've got information about an update 11.03.
(1) Is it correct, that the hole IA-software (including all runtimes) is installed by new with this update? Is there any way, only to install update-files? How can I be sure not having lost anything created by myself?
(2) Dose it make sense to install all runtimes, even if I do not need them for the moment, or is it better to do a minimum-installation now and re-install runtimes, when I need them?
(3) How can I check my currently installed version of IA (11.01, 11.02, ...)?

thanks, Norbert

Dear Norbert,

(1) IA 11.03 is indeed a more "major" release and therefore required an entire installation. There is no way to avoid this. Your projects, though, are not deleted, and if you have any custom runtimes, just back them up from the runtime folder.
(2) I recommend installing all runtimes, unless you are concerned with disk space. Otherwise, any runtime might come in handy one day..
(3) You can see the version when you look at the InstallAware entry in the Add or Remove Programs in the Control Panel.
