; MSVC Redistributable - required if the user does not already have it
; Note: if your NSIS generates an error here it means you need to download the latest
; visual studio redist package from microsoft.  Any redist 2008/SP1 or newer will do.
;
; IMPORTANT: Online references for how to detect the presence of the VS2008 redists LIE.
; None of the methods are reliable, because the registry keys placed by the MSI installer
; vary depending on operating system *and* MSI installer version (youch).
