Install permission /need answer!

I've made EXE-replacing installer (graphics patch, *not* crack).
To relace EXE user must locate game's folder containing original EXE (by using the Browse button). When he locates it, he clicks Install and everything is OK. But here's my question: Can I disable Isntall button if specified directory do not contains original EXE? (EXE to replace) 🙄
Please help! Its important!

Use the .onVerifyInstDir callback function.

Rather than disable it, it would probably be better to have a message box stating why the user cannot click the Install/Next button.
Something like this:

!define MUI_PAGE_CUSTOMFUNCTION_LEAVE "checkPath"

!insertmacro MUI_PAGE_DIRECTORY



Function "checkPath"

 IfFileExists "$INSTDIR\executable.exe" +3

  MessageBox MB_OK|MB_ICONSTOP "The entered path does not contain the correct executable: executable.exe.$\r$\nYou cannot continue!"

  Abort # Go back to page

FunctionEnd
