I’ve just tried to open Rhino 5, 64-bit, after a few days not using it, and it won’t start. I am taken directly to the McNeel Error Reporting window. I browsed here and people have suggested Safe Mode and disabling plug-ins. I tried to open it in safe mode and the splash screen shows for literally a fraction of a second, then straight back to the error reporting window.
I have tried to update the software. I downloaded an update for 32-bit first, which installed fine. I then downloaded the 64-bit update, and it will not start. Instead, I am given a “fatal error” by the installer, after it computes space requirements. Similarly if I go to Control Panel/Repair, it starts the process and produces a “fatal error”.
Bit flummoxed by this. Does it sound like the program is corrupted? I can try reinstalling from CD in a week or so, when I get back home, but if people have suggestions in the meantime that would be great.
