installlib not found

Hi I am getting the error

macro installlib not found when inserting this code :


!insertmacro InstallLib REGDLL $ALREADY_INSTALLED REBOOT_NOTPROTECTED \
"D:\Program Files\PDF Split Merge Component\PDFSplitMerge.dll" \
"$INSTDIR\PDFSplitMerge.dll"

it is in the MUI section

I copied the text strainght from the help file and then amended it.

many thanks

Andy

did you include Library.nsh?
!include Library.nsh
NSIS manual Appendix B: DLL/TLB Library Setup

Did you !include "Library.nsh" ?
