Perhaps the reason we get no crash logs is that your system is set not to create crash dumps. Try this procedure (from here):
On Windows, applications no longer produce a crash dump by default. You can make your computer generate the minidump files we need to diagnose your problem by downloading, unzipping and double-clicking this Registry key:
dump-config.zip (469 Bytes)
Now when Dorico crashes, open a Windows Explorer window and go to %LOCALAPPDATA%\CrashDumps (you can copy and paste this into the address bar), then zip up the files you find in there and send them to us.
You shouldn’t need to manually collect the crash dumps, in fact: once this Registry key is set, when you create a diagnostic report, Dorico will collect the crash dumps for you.
