The babylonrpi.api file is an Adobe plugin for the Babylon translation program. Without this file, Babylon translation services will not be available in Acrobat reader or other Adobe programs. If you get an error that includes this file, it may have been moved or the registry lost track of it. Adobe plugin files need to be located in a sub folder of the Adobe program. You can attempt to locate the file and manually move it to the correct spot, or you can have ZookaWare PC Cleaner scan your computer and fix the problem for you.
In order for programs on your computer to work smoothly, the registry needs to have current information on where all the pieces of the program are located on your drive.

If you use ZookaWare PC Cleaner, you don’t need to worry about figuring out where files belong.
