Im using the below code in
Function .onInit to display the selection box in the beginning of the Installation
!insertmacro MUI_LANGDLL_DISPLAY
When i compile my code it throws the below warning message and as a result No selection box is displayed.
unknown variable/constant "{MUI_LANGDLL_LANGUAGES_CP}" detected, ignoring (macro:MUI_LANGDLL_DISPLAY:27)
when i clicked on the warning message , It took me to the system.nsh file and highlighted the below line
LangDLL::LangDialog "${MUI_LANGDLL_WINDOWTITLE}" "${MUI_LANGDLL_INFO}" AC ${MUI_LANGDLL_LANGUAGES_CP} ""
P.S : The selection box works fine when i created sample installers.
