Uninstall Function Not Working
I am trying to call a custom function before the welcome page in my uninstaller using the command below

!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_FINISH

ShowUninstDetails show
!define MUI_UNPAGE_CUSTOMFUNCTION_PRE un.warning
!insertmacro MUI_UNPAGE_WELCOME
!insertmacro MUI_UNPAGE_CONFIRM
!insertmacro MUI_UNPAGE_INSTFILES

And the functions is as follows.....

Function un.warning
MessageBox MB_ICONEXCLAMATION|MB_OK "Test Warning Message"
FunctionEnd

When I compile I get the message.....

uinstall function "un.warning" not referenced - zeroing code out

The message doesnt get displayed, I am assuming the call is being cancelled out, anyone any ideas where I am going wrong?

Use MUI_PAGE_CUSTOMFUNCTION_PRE, even for uninstall pages. MUI_UNPAGE_CUSTOMFUNCTION_PRE is not correct.

Thank Afrow!

So it is the name of the function that needs to be prefixed with un. - Not the call itself?

I'm not sure what you mean. What call?
