Two years ago I bought Adobe Photoshop CS6 Extended and InDesign CS6, with lifetime licenses. Now Adobe claims that these programs are illegal. So I would like to buy these two programs legally, with a lifetime license for one computer. I don't want any other support programs, cloud storage or other add-ons. I would like to buy the so-called "box" version with a disk or USB flash drive, so that I can always upload the program to a new computer. Where can I buy these programs and at what price? I am over 70 years old, retired and my income is small. So I expect the lowest possible price.
Unfortunately, Adobe has stopped selling lifetime licenses for these softwares and only offer subscriptions now. Also the versions you are after are pretty old so sooner than later they would not even be able to properly run on mordern versions of OS and then then there is a risk of Adobe killing the activation servers for these versions as they have already done till CS4. If you are very tight on budget, I would suggest the following options.
Two years ago?
Adobe and all authorized sellers stopped selling "perpetual" versions long before that. You did indeed buy illegal versions and there is no way to buy them legally.
read both posts above. they both contain useful information.
but to answer your question directly, you cannot legally purchase a cs6 license. any cs6 license you do purchase is being sold illegally and will be subject to revocation just like your purchase from 2 years ago.
If it's a used version and the current owner of the license transfers the license through Adobe, it can be done. But that's the ONLY circumstance under which it can be done and finding a legal used version with a transferrable license is a bit of a c**pshoot. There are no legal new versions available from anyone.
Note that you also need to ensure that the license wasn't originally sold to a corporation as part of bulk purchase, since those cannot be resold.
Photoshop Elements is available as a one time purchase.
InDesign is not available without a Creative Cloud subscription.
the least expensive way to legally purchase would be to subscribe to the photography plan (ps and lr) and subscribe to id.
