Need licence key for my perpetual substance painter 6.2.2

https://substance3d.adobe.com/faq-end-of-life-accounts/

That page has instructions about how to get your key from Adobe if you have an Adobe account as well as if you do not have an Adobe account if you purchased through the substance website before it was shut down in 2022.

I was unable to find the .key file in my adobe account

If it is not in your Adobe account, then you will not be able to retrieve it.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
