Display html from finish page
I cannot for the life of me get my installer to display the a html readme in the finish page
I have defined
!define MUI_FINISHPAGE_SHOWREADME
!define MUI_FINISHPAGE_SHOWREADME_TEXT "Show Manual"
!define MUI_FINISHPAGE_SHOWREADME_FUNCTION ShowReleaseNotes
Function ShowReleaseNotes
ExecShell "open" "$INSTDIR\hl2coop\Docs\index.htm"
FunctionEnd
What am I missing?
