I installed the 64 bit FileMaker Pro 14.0.6. A dialog box popped up directing me to go to the control panel and set my default mail app. Windows 10 recommends "Mail" as the default mail app. I also tried "Windows Mail Live" as a default. In both cases I keep getting an "unknown error: -1" message when I click on the e-mail button on the layout. This was the same problem I had before when using 32 bit FM Pro14 on a 64 bit machine. I've looked at what's online, nothing I found works. Do I need to install an email app that will work?
