running version 12.0v5 (09-11-2013) Unexpectedly quit message again and again. Nothing will open. Update therefore not possible.
What OS are you running FMP12 on?
That's going to be your issue. FMP 12 isn't tested or support on 10.14(Mojave). The highest FMP 12 was tested and supported on was
It's going to constantly have issues on an advanced OS like Mojave. I recommend that you discontinue using FMP12 on that machine until you can update your FMP. The more you try to force it to work and the more it crashes, will increase the likely-hood that your database becomes corrupted from the crashes. If you need to continue to use your database(s), download the trial of FMPA 17. It will give you 45 days to figure out what you would want to do.
OK Many thanks.. Ill quit wasting time trying to get the thing to open.
Running FMP12 in a Virtual Machine is another option. If you have the hardware specs for it, spin up a VM of something earlier than El Capitan. That can hold you over until you are able to upgrade to a newer version.
Parallels, VMWare, VirtualBox ( free ) should all work for you. I've not tested VirtualBox installed on a mac. So I'm not 100% sure on that one, but I feel like it should be fine.
