Hello again all.

I have finally managed to download some free software, but am now having problems opening the application.

The program starts to install and then stops at a prompt.
Open file. The publisher could not be verified. Are you sure you want to run this software?

Also, this file does not have a valid digital signature that verifies its publisher.

I filled in the personal license key that i was sent after registration, but don't understand what digital signature is.

I have also noticed that the download is only 194 MB of a 550 MB file. I am guessing that there is more to come once the publisher as been verified.

Can anybody explain what i am doing wrong or what i require?

The software, is a CAD package called Medusa 4 from CAD Schroer

Cheeers in advance.

Steve.
