I have created a project and copied the cipher50.fll (encrypting and decrypting) library file into my directory. I have included the library file in my project. When I try to run the application (EXE) after compiling it, it runs fine. I have other users that are running it OK; but I have some when they try to run it the get "Invalid library file" when the "SET LIBRARY TO cipher50.fll" code is initiated. Can anyone help me with this?
