Cannot finish installation on pc

Hello,
My husband tried to install the game on his windows 10. He was done with all the DVDs and then he wanted to start the game.
An error message appeared, something like: “wrong disk” … and he couldnt start the game.
Any idea what the problem could be? Sorry, sometimes my english is a little weak …
It took a lot of time to finish the whole installation with all the four or five disks and then an error message. He wasnt able to start. No idea what I could tell you more.
He has a good pc for this game and he uses windows 10
Hope you can help :wink:

no one out there who can help my husband? :wink:
I try to reproduce the problem. He has a good computer for all those new games. He starts the installation process and gets no error until he reaches the last DVD. Then when the last DVD is done he tries to finish it. There it says: “wrong disc, the installer is not working” … any idea what this could be?
