In reference to that thread and final answer by Nancy, that is not true. I am well aware how long I have owned and used this software. I purchased it legally and have been using it ever since across MULTIPLE computers over the last decade and NEVER had to UNINSTALL when moving onto the new computer. In almost every case, the old computer hard drive physically died and there was no way to UNINSTALL the software. Never had this problem. Now all of a sudden I am being hit with this 2 computer limit after a decade of use. The software I own, still installs on Windows 11 and works correctly until this crap about registration.

There was never an EXPECTATION that I needed to upgrade to an overpriced subscription model when I have fully functional software I legally purchased. There is no reason Adobe should be blocking users from using something they legally purchased. I am well aware it is "no longer" supported and updated. For the kind of work I do, I have never needed anything your new subscription model offers other than way too much cost.

And this "customer service" based on that original thread shows to me that Adobe does NOT care about its long term customer base. I have been a valuable "customer" since Photoshop was version 1. This reflects an utter disregard for the "old" customers who have a legal product that works and Adobe is now blocking us from using it in a chase for more money.

For everyone that is correcting my "installation" of CS5 two installation rule, I don't know what to tell you but that has never been true for the software I have been using for over a decade. The old computer dies a horrible death, no possible way to uninstall. Maybe people don't understand that a hard drive dying is not possible. Grab my old box with the installation CDs, install it on a new computer, put in the registry information, and it worked like a charm. Always has for me. So please understand you can claim whatever, but I AM the one who has been using and installing this software for the last decade or so, not you. And if these others have never experienced a computer failure where everything is lost and a new computer purchase is required, call yourself lucky. But many of us have not been so lucky and have had to spend countless hours re-installing old software time and again from old installation CDs. There was no reason for me to expect a different outcome this time compared to all of the other instances.

 

Regardless of that, it still doesn't excuse Adobe dumping on old users. IF THEY can "validate" it is installed on two "old" computers then there is some mechanism that is still operating to check. To then turn around and claim they can no longer validate my installation because the servers "no longer exist" when they just CHECKED the validity of my installation shows this is not entirely correct. They are checking against a database of some sort so should be able to assist with validation concerns of a legally purchased piece of software, regardless of age, because they are STILL checking the registries.

@Gumbytie you're getting your terms mixed. You are correct that you do not have to uninstall the software, however as others have pointed out in the main thread and on here - you have to deactivate your license in order to use on another computer. There is a difference. The only recent change was enforcing already existing agreements and no longer extending or adding activations to the license. If you are able to deactivate previous installs, then it would still activate and work.

There is no way to de-activate software on a computer that no longer exists. So I am splitting hairs on terminology but the frustration comes from a situation that should not be occurring. As the old computer suffered a failure much like ones in the past, there is no way to "de-activate" anything on the computer. The hard drive NO longer functions. Again, if none of you have ever experienced something like a complete hard drive failure, all the best. But it happens. And there is nothing to be done about ANY software installed on it. I have never had this problem before using the specific piece of software or any others under similar circumstances. That is the point of my post and complaint.

we understand there are several situations where it's impossible to deactivate an activation slot.  there's just nothing that can be done to change that and no other way to open a deactivation slot.

Look, Adobe CS5 rules only allow the users to have 2 activations at at time. And if you want it to install on other new computer, you first have to deactivate it on the older computer.

It sounds like Photoshop Elements is more suitable for your needs. It can already do more than CS5 could, plus it will be written for modern operating systems.

 

It has never, ever, been possible to exceed two activations. A third install always required deactivating one of the previous. Don't know what else to say. It just wasn't possible.
