...auto-download during installation. Harmless details like that can make some people go crazy in a non-productive way

As unfortunate as that (user)behavior may be, the JottiQ installer really throws a big Yes/No messagebox, listing all prerequisites and their sizes, at the user
if (any of) the pre-reqs need to be downloaded and installed.
It might be a good practice to pre-announce that with the download-link (but
not offer any links), so a really paranoid user can download these pre-reqs himself from the source he wants/trusts.
This installer downloads the proper web-installers from Microsoft and installs the frameworks, including their proper language-packs, as and if required by the OS at hand.
Undesirable workaround hidden here...
If it gets really problematic, I could add a feature to select something like changing the Yes/No to Yes/No/Cancel, to either Yes:download & install, No:skip the pre-reqs & continue or Cancel:halt the complete installer, but that could lead to a non-working installation of JottiQ (or anything else that uses the script-parts I used) and would not really be desirable, IMHO.
