I bought Adobe CS5 Master Collection years ago on a perpetual licence at full price, which is supposed to mean I can install and use it for as long as I want, on whatever machine I want. Adobe allows two active installations at a time, so when you get a new device you deactivate the software on the old one and activate it on the new one. I've done this a couple of times over the years without any trouble.
I got a new laptop recently. This time, I deactivated it cleanly on my old laptop, then went to activate it on the new one and the activation process timed out. There was no error that made sense or obvious path forward, just silence.
After digging around online I found out why. Apparently, Adobe quietly switched off the activation servers for legacy pre-subscription software in 2025 without telling anyone.
I've never asked them to support the software. What they've actually done is remove the mechanism that lets someone who legally bought a perpetual licence activate their own product. There's a Consumer Rights Wiki page documenting this, and some Reddit threads and here full of other people describing exactly the same runaround.
I feel like I've been battling Adobe's bullshit for years. I tried (and failed) to upgrade to CS6 back in 2013 when they first started trying to force everyone onto Creative Cloud, and in 2015 I struggled for hours just to get routine software update to install due to their poor form. In 2017 I asked them how to use my product on a high resolution screen and their only advice was to upgrade, which was technically wrong - a guy called Dan Antonielli had already published a registry fix in 2014 that solved it without any Adobe upgrade at all, and when Windows finally added its own native high-DPI override in 2019, he documented that too. Neither fix cost a cent or needed a subscription.
Thirteen years on, it's the same company finding a new way to push the same outcome. I'd like to say they are the epitome of enshittification, except they haven't gradually enshittified, they've always been shit to their legacy customers.
What actually happened
The case history is worth laying out because of how many times I had to start the conversation from scratch.
- Case 1 - ADB-45560212-Y9G0 (3 June). Opened and closed the same day. The summary field says "informed regarding EOL," which is Adobe's way of telling me the product had reached end of life without offering anything resembling a fix. I replied two days later refusing to accept that, but by then the case was already closed, so my reply bounced to an unmonitored inbox.
- Case 2 - ADB-45614666-D7P5 (5-11 June). Reopened through chat and told the backend team would review it. Five days later they came back with an offer to sell me a Creative Cloud subscription at a discount, which wasn't what I'd asked for at all. I said no, told them I wasn't interested in renting software I already owned outright, and pointed them to the Consumer Rights Wiki page and Reddit threads. They escalated again, and two days after that issued a new serial number, which turned out to be invalid. They closed the case before I had a chance to tell them that, so I had to wade back in again.
- Case 3 - ADB-45714968-L0H3 (closed 12 June). A dropped chat, closed with the explanation "sorry, we were disconnected" and nothing resolved.
- Case 4 - ADB-45761286-P4T8 (16-17 June). The agent ran a remote support session and worked through everything I'd already reported, finding nothing different to what I'd already told them. He said he'd escalate it. I woke up the next morning to find the case closed, with no further communication at all.
- Case 5 - ADB-45818350-V0L7 (19-23 June). This is the one that worked. I got through to an agent called Paridhi, who actually engaged with the problem. I had to point out myself that the "new" serial number from Case 2 was for CS6 rather than my actual product - when I asked why I'd been given the wrong version, I was told they'd assumed I'd appreciate the extra features - and Paridhi escalated it properly. My product is CS5. It doesn't have CS6's features, because it isn't CS6. A new, working CS5 serial number arrived within 24 hours.
The best part of a month, 5 case numbers and 2 serial numbers, one of which was for the wrong product entirely, on top of a dropped session, a session that vanished without explanation, and an outright refusal dressed up as a routine end-of-life notice. Not everyone I dealt with was as capable as Paridhi. A few of the advisors along the way genuinely didn't seem capable of troubleshooting or resolving anything. Closing tickets seemed to be the actual goal rather than fixing the problem, which made me wonder if that's a training issue or a KPI. I'm not even sure if there was a single reason it finally got sorted, but I was prepared to keep pushing.
Being handed back what I already own, framed as a favour
When the working serial number finally turned up, it came with a condition attached: a limit of two future activations, with me responsible for managing them from here.
That's presented as a concession, as if letting me use software I already paid for in full is something Adobe is generously extending to me rather than the bare minimum they owe a customer who bought the product outright. I own this licence. Adobe doesn't get to decide, after the fact and off the back of their own decision to shut down the servers, how many more times I'm allowed to install it.
If you're here because the same thing happened to you
Given that my 2015 CS5 update post is still the second most visited page on this blog after all these years, there's a decent chance you found this the same way. A few things that helped.
Understand that this is deliberate, not a bug. Adobe retired the CS5 and earlier activation servers on purpose, and there's no self-service fix or working offline activation option. Some of the "solutions" floating around online involve replacing DLL files with unofficial downloads, which I'd avoid entirely given the security risk and the likelihood it breaches your licence terms anyway.
Don't accept the first no. Every case that got closed without a fix was closed by someone who either couldn't or wouldn't escalate it properly. The one that worked only worked because I kept going back and eventually reached someone who took the problem seriously.
Cite the paper trail. Referencing the Consumer Rights Wiki page and the Reddit threads in my emails visibly shifted the tone of Adobe's replies. It tells them you already know this is a documented, ongoing issue rather than something you've stumbled into alone.
Ask for the case to stay open until you've tested the fix. Not that this actually worked - hence my 5 case IDs - but it's worth asking anyway so it's documented. The first 4 of my cases were closed before anyone confirmed it actually worked, but Paridhi could see this had occurred within my account and they committed to keep the case open, and actually did follow through.
If you're in Australia, mention the ACCC. This behaviour is a breach of Australian consumer law. I couldn't tell you whether it would hold up as a formal complaint, but every little bit helps.
This wasn't incompetence, it was a decision
Adobe have spent years trying to entice perpetual licence owners onto Creative Cloud. It didn't work on me because there's nothing in the subscription that's worth the additional cost to someone who already owns the software outright. Once persuasion failed, they moved to the next option: if you won't switch, you can be forced to. Switching off the activation servers isn't a cost-cutting decision about old infrastructure, it's a deliberate move against exactly the customers who'd already said no to the upsell.
I'm not a lawyer so I can't say this is illegal. But deliberately disabling a paying customer's ability to use software they own outright, then handing it back with conditions attached as if it's a favour, is unethical at best.
I will never pay Adobe another cent. Between open source tools and general purpose AI now handling most of what I'd have reached for Photoshop to do, I don't need to. Adobe knows the subscription pitch didn't land with people like me. I suspect that's exactly why they stopped dangling the carrot and decided to brandish the stick instead.
I got there in the end, but it took the best part of a month I shouldn't have needed to spend. Most people don't have that kind of time, and Adobe is almost certainly counting on that too.
