How can I get Premiere Pro 2017

>full bootable backup of your computer

Hardware crashes or virus infections or simple software problems happen, so you should buy AND USE software to make a full backup of your hard drive to an external USB hard drive... plus, making step-by-step backups during a new setup or major program addition makes it easy to go back a step if something doesn't work... I have had to do this once when a program install didn't work properly (a different program, not Adobe) and I had to do a restore due to my drive being SO messed up that I couldn't even uninstall the bad program
.
This backup and then restore is, of course, only to the same computer with a new drive (or the same drive as long as you don't mind writing over everything) since doing a restore to a new computer requires extra steps due to Windows and many programs having activation information that is keyed to your hardware (which is why Windows will force you to RE-Activate if you change very much hardware)
.
The product I bought and use is at http://www.terabyteunlimited.com/image-for-linux.htm
Note that I get NO benefit if you buy the program, I only use it and like what it does
Version 3 allows restoring to a larger drive and expanding the partition to fit
.
Image runs off of a bootable CD via Linux (the Zip you download includes a program to make the bootable CD) and it reads EVERYTHING on the drive, even the hidden registration information, so everything is restored when needed... and you may not only restore the image over a messed up install, you may restore to a brand new drive in case of a hardware crash, and not have to re-install anything

First off, do you not have a full bootable backup of your computer before it died? Not sure if you're working on a new machine or you got your old one up and running again -- but if it's the latter then having a full backup means that you can rebuild your system easily, including apps.

That said: try this link and see if you can get the 2017 installer onto your computer; it should still work with yout license:

I believe that link still works; if not then we need to guide you into getting that project updated to a newer version.
