Ligftroom 6 perpetual licence?

I have a laptop which is 9 years old and therefore should be replaced.

In that old laptop I have Lightroom 6 stand alone version. I purchased it in June 2015

Now I have a problem. I purchased a download version, so I do not have a DVD or any similar disc for the reinstallation of Lightroom in the new laptop. Neither do I have the exe-file for installation.

I know Adobe has changed Lightroom to a cloudbased application with monthly payment. It is not, however, suitable for me. I am not a professional photographer, but rather a guy takes photos when travelling, in family parties and so on, so not a heavy user.

When I got Lightroom in 2015 it was said to be perpetual. So my question is this: is there any possibility to download Lightroom 6 for the reinstallation or do I have quit that application just because I am going to have a new computer. I would consider that rather unfair, perpetual licence as I said.

I know there will not be any updates and improvements, but that is not a problem for me. I am satisfied with lightroom as it ia now.
