Hi
Sorry for what must be an easier answer, but it is driving me nuts.
I know you can use Prerequisites to tell the installer to check if a file is already on the users system, before the installer will continue.
However, I have also been trying to use Custom Actions (Search), to display a custom error message if a certain file isn't found, but havent had any joy.
Could someone explain to me what I need to set up to do this?
I added AppSearch/Error mesage, but don't know what criteria to use.
I am obviously using the wrong criteria, but either my error message shows regardless, even if the file is on the users system, or it doesn't show, and installs anyway, even if the file isn't there! Depending on what (wrong) criteria I use
Sorry
