Successfully installed DOPUS Directory Opus 9.5.6.0.3937 x64 on Windows 10. Attempting to restore my saved configuration OCB file from WIndows 7 has crashed DOPUS.
If you get a crash importing the same config into Opus 12 then we can analyze that, as long as you link your account, but Opus 9 is too old for us to analyze crashes for, and also too old to get updates now.
The first Opus 9 version came out a decade ago, eight years before Windows 10. It is ancient now. Opus 9 was given free updates for three and a half years. The last Opus 9 update is seven years old at this point, and that was five years before Windows 10 even existed.
