I wanted to submit this, but didn't want to edit the article since I'm new here.
Use ${GetSize} to fill in the EstimatedSize value. This assumes the simple case where there is one main directory with most of your files (including subdirs).
Just the relevant bits of foo.nsi :
!define ARP "Software\Microsoft\Windows\CurrentVersion\Uninstall\${APPNAME}"
!include "FileFunc.nsh"
Section "Install"
; [...copy all files here, before GetSize...]
${GetSize} "$INSTDIR" "/S=0K" $0 $1 $2
IntFmt $0 "0x%08X" $0
WriteRegDWORD HKLM "${ARP}" "EstimatedSize" "$0"

Computing EstimatedSize, Method 2.
Make sure you ClearErrors when using the GetInstalledSize function to compute the EstimatedSize, otherwise the loop will end prematurely. You can also ClearErrors in the function itself.
