Updating to a new Computer, cannot find anywhere to download Trados 2017 to utilize my perpetual license on it

I have had several versions of Trados, and updated promptly most of the time. But I was in the middle of an international move when the last upgrade window from Trados 2017 closed, and was then stuck with this version.

Now, with my latest computer upgrade, I cannot find anywhere to download Trados 2017. My "perpetual" license would then be worthless, unless I use it on a computer that's about to die.

Is this the case, or is there a hidden place to download this version?
