Add-on connection timed out. (when trying to start add-on)

This is an indication that you tried to run an add-on but the SAP Client failed to register that it started. There can be several reasons for this:

• I get an unexpected error from the .Net Framework during launch. This often indicates incorrect permission rights. See the "Unexpected error on startup" section for more.
• The add-on was installed on a shared folder (This result in an unexpected Security Exception when running the add-on). Solve this by uninstalling the add-on, and reinstalling it on a local drive.
• The machine is simply too slow. Please try again and if running many programs, please try to close all but the SAP Business One Client.
