Distinguish Win9x <-> XP, W2k
Hi there,
I know the plugin to get the current Windows system/version. But I don't know how to use it to activate different parts of the code (a simple "IF.. ELSE ..").

Anybody knows the solution for doing that?

Background: under Win9x I have to make an entry in the registry to install a service, else I'm using the Service plugin.

Tjis code should help you out (derived from the nsis help file):

  Push $R1
 
  ReadRegStr $R1 HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion" "CurrentVersion"

  IfErrors lbl_win9x lbl_winnt

lbl_win9x:
  ;insert code for 9x here
  goto lbl_end

lbl_winnt:
  ;insert code for nt here
  goto lbl_end

lbl_end:

  Pop $R1

Check for the registry key

HKLM, "SOFTWARE\Microsoft\Windows NT\CurrentVersion", CurrentVersion

When it exists, it's Windows NT (NT4, 2000, XP).
