Start the air app and select your “project cache location” using the “Browse” button (the default location is” My DocumentsAdobe Captivate Cached Projects”). Now click the “Refresh” button. This will list all the project names for which the project cache folder is available.
3) Check if you can see your project (which is not opening in captivate) listed there. If yes, then double click on that row in the air app, this should display a dialog containing the “Cache Path” as shown in the image below.
