License for Nitro 6 and 7

[Tomas Battistini]

Hi, in past years I bought 3 licenses for Nitro 6 and one license for nitro 7
Now the users' computers where I used them have been returned to me, these people are gone and the computers have been formatted
Can I use these licenses on new comptuer? Do I have to download and install old versions of Nitro of the same version? Where can I find them?

Best Regards

Tomas
