I have a runtime solution built in FM14. The user is running it on a PC (64bit). When she installed the runtime, started entering data and hit the send mail script it worked fine. The script created the mail content, called on her default mail app, populated the message and she was able to send the message. Then one day that stopped. Worked fine on a tuesday, quit working on a wednesday and still hasn't worked. She did nothing to change the files of the runtime or her mail client. I assume her PC is blocking the FM - mail app communication.
What do I tell her to make her mail client work with FM again?
