No real need for this plugin as the System.dll plugin alread can do this. Check out this code:
; Just a key to store a window handle in !define PLUGIN_INSTREGKEY "Software\My Company\My Product" Function .onInit System::Call 'kernel32::CreateMutexA(i 0, i 0, t "NxSBalloonTipPluginSetup") i .r1 ?e' Pop $R0 StrCmp $R0 0 noprevinst ReadRegStr $R0 HKCU "${PLUGIN_INSTREGKEY}" "WindowHandle" System::Call 'user32::SetForegroundWindow(i $R0) i ?e' Abort noprevinst: FunctionEnd Function .onMyGUIInit WriteRegStr HKCU "${PLUGIN_INSTREGKEY}" "WindowHandle" "$HWNDPARENT" FunctionEnd Function .onGUIEnd DeleteRegValue HKCU "${PLUGIN_INSTREGKEY}" "WindowHandle" DeleteRegKey /ifempty HKCU "${PLUGIN_INSTREGKEY}" FunctionEnd
This code also brings the running instance of the installer to the foreground if starting another instance.
