I use a Lumerical FDTD Solutions for the first time.
I received a trial license but FDTD Solutions didn’t run. It happened because I used the computer on which trial license was installed before. So I have to contact with Account Manager to explain this situation and he sent the new trial license to me soon.
Thereafter I added this new trial license to the first trial license. But FDTD didn’t run and I decided to remove and to reinstall both licenses.
First of all, I removed one of them. After that I have tried to remove the second license but I have failed (look at the print screen).
Please tell me how can I fix this problem?
