You may get the message “AIT script files must be in a sub-folder of the GP installation folder” when running the AIT Setup Wizard. This message happens when you are trying to read files located in a folder (such as a network share) that is different from the current Dynamics GP installation location. You must select the folder that matches the current GP installation location.
This restriction was added to avoid problems that could happen if you installed the wrong SQL stored procedures. All downloads are designed to install SQL script files in a specific folder and these files must match the build you have installed.
Never copy the script files from another computer or installation!
