thanks Red Wine

this link was really informative

still one doubt

the return value of FindProcDLL::FindProc will be captured in $R0 but how to test this value

i mean how to put condition on $RO

Better yet, use the LogicLib.

!include LogicLib.nsh
#...
${If} $RO == "something"
  # do something
${Else}
  # do something else
${EndIf}
