Regarding use of HKCU vs HKLM (split from general Installer thread to be
focused on this issue alone) :
Here is some sample code for a custom page allowing choice of "Just this
user" and "All Users". It is pretty stripped down just to illustrate the
basics of how it works.
(I haven't tested with a "limited user" account to see what happens. I
suppose that could be detected with Contrib\UserInfo\UserInfo.nsi and only
allow "current" and don't even show the custom page ... my impression is
that a "limited user" can still read HKLM)
