Pull the hard drive from your dead computer and install it to a drive bay in the new machine.
First- Download and install Command center from your account.. don't run it yet.
This next step avoids re downloading the files again--
Go to old drive / Program Data/Cakewalk/Command center/downloads and copy that to the same location of your new C drive.
Now run Command center and it will use those files and all will go super fast.
I'm just doing this now as I type as I put a new SSD in my laptop and starting fresh.
Command center speeds up the installation 10 fold over doing it manually.
If any of your files were out of date it will download the newer version and ignor the old ones.
And you will want a copy of that download folder stored somewhere safe.
Also for future proof you can go to your "my Products" page and make screen shots or copy paste all your serial and registration codes for all your products.
