I have a C# (MS Visual Studio 2010) program that has always used a ms access 2003 database with jet engine 4.0. I had to convert the database to a 2013 Ms access database; the application now works on my development computer, but when I deployed the application, I received an authorization failed message. When running the application initially from my development computer I received a jet engine not registered on the computer message. Are these errors related? Do I need to install the access database engine on the computer that will receive the application?
