SD closes without any error message

[klmorin]

I just installed SuperDuper on a new computer. I want to create a sandbox on a partition of the internal drive. I do the usual way, I click "Copy", the activity window appears fraction of a second and disappears. SD closes without any error message. An explanation?

Sounds like you copied it from another Mac. Try a fresh download.

You are right. Everything is well now.
Thank you very much.
