CS6 Master Collection perpetual license – orphaned activation cannot be deactivated

I legally own a perpetual Adobe Creative Suite 6 Master Collection license.

The Adobe activation server reports that my serial number is already activated
on two computers. In reality, I currently have access to only one activated
computer. The second activation belongs to an old system/computer that no
longer exists, so it is impossible for me to deactivate it locally.

My Adobe account shows no activated devices, which is expected because remote
device deactivation is only supported for Creative Cloud applications.

I am not asking for technical support for an unsupported CS6 application.
I am asking Adobe to correct/reset an orphaned server-side activation record
for a perpetual license that I purchased.

Could an Adobe employee please escalate this to the licensing/activation team?

I can provide the serial number and proof of purchase privately if required.

Thank you for posting, @mbienkowski.

I appreciate your long-term use of our software.

I can confirm that you have an activation remaining for Master Collection CS6 for Windows. What exact error message are you receiving when you try to install the software, @mbienkowski?

If you need to reinstall, you can download the appropriate CS6 installation files from:

Download non-subscription Adobe software

For current information about signing in and activating CS6 on Windows, please review:

Signing into and activating legacy Adobe applications

If one of your previous activations is tied to a computer that is no longer accessible and cannot be deactivated normally, please also see:

Activation limit reached for non-subscription Adobe desktop applications

That document explains the options available when a prior installation cannot be deactivated before the hardware is retired or becomes unavailable.

Make sure you use the correct installation files, @mbienkowski. People often confuse the invalid serial number message with activation errors. Using the correct installation files for your serial number can help resolve this issue. If you continue to encounter problems, please let us know the exact error message you receive. Since you still have an activation available, we need to determine whether you are seeing a serial number error or an activation error.

Please let us know if you are reinstalling on the same computer, migrating to a different Windows PC, or attempting to recover access after a hardware failure, as that information may help the community provide more specific guidance.

If you’re dealing with an orphaned activation on a CS6 Master Collection perpetual license, the old activation usually needs to be cleared or reset before the license can be activated on another computer.

Adobe does NOT reset activation counts.

The only way to deactivate a license is from the machine it was installed on.

Unfortunately, most machines from the CS6-era are dead or recycled which makes deactivation impossible.

Hello, thanks, I have one activation left since I deactivated software on the computer I am using to reinstall it. I will review this document. The second activation has probably been lost after hardware failure (or more - probably decomissioning some old laptop without deactivation)

CS6 was built for Win Vista, Win7 & Win8 platforms.

It was not built to run on Win11.

Best advice: keep unsupported legacy apps on currently installed device(s) and use for as long as you can.

Get supported apps for new devices.

Post back if you need recommendations.

Good luck.

As @kglad has already said, even Adobe employees can’t do it anymore. CS6 has been taken off life support entirely. For more expanded discussions, you can see the thread below (as well as look for other threads on the subject):
