I am at a loss. I have been using Adobe Lightroom Perpetual License since 2018. I just got a new computer and they are telling me I can no longer download it because it is discontinued.

Thank you I will try that

I think you’re talk about Lightroom 6. Here you'll find the appropriate installations files.

• Mac: https://web.archive.org/web/20231114161051mp_/https://prdl-download.adobe.com/Lightroom/60BA1251F1BC...
• Win: https://web.archive.org/web/20231220005239mp_/https://prdl-download.adobe.com/Lightroom/60BA1251F1BC...

Please be patient, the downloads can take several minutes to start and can proceed slowly.

I'll recommend to save the download files on an USB stick, hard drive or CD/DVD, but it isn't sure how long these links are available.

If the normal activation process doesn’t work try to do a offline activation.

See @Eldiin's post here: https://community.adobe.com/t5/lightroom-classic-discussions/lightroom-6-sign-in-required/m-p/150655...

But be aware: if you have reached your activation limit and you don't have any chance to deactivate an older installation you're out of luck. Adobe has stopped the support of Lightroom 6 and the resetting of the activation counter isn't possible anymore.
