Unable to activate Master Suite CS6 on a new Windows 11 computer

[Arto15B9]

Hi, I have CS6 Master Suite active on two Windows 10 computers. I just purchased a new Windows 11 computer and installed the CS6 Master Suite from original DVDs on that and all went well, but when I tried to activate it on the new computer I got a screen that said I have it already activated on maximum number of computers.

So I went on and deactivated it on the other of the two old computers I had it active. Deactivation was successful (I did not via Adobe Photoshop CS6 64-bit version). But that did not decrease the count of installations, so I keep on having the message on the new computer that I have it activated on too many computers. 

Now I am afraid that if I retry deactivating on either of the old computers, I lose a working Master Suite on either of them. I wonder if this can be worked around in some way as it seems to be an issue with Adobe servers not actually decreasing the count of activations, but just keeping the current activations alive as long as those computers are alive. Or could this be related to Windows 11 somehow?

The official chat support asked me to post about the issue here on the community, I hope you can help. Please let me know what you need to know about installations.

I have also Photo CC subscription active (now that changed to be active on the new Win 11 computer and one Mac M1 computer), and Adobe Acrobat Pro 2020 (perpetual license) on two Windows 10 Pro computers. And several other CS based licenses active on other Windows computers, but with separate serials, up to CS3 on computers as old as running Windows XP. So I have been happy to run CS based apps this long. I know that I cannot activate such old CS based versions (on anything), as activation servers are dead (at some time Adobe gave special versions of e.g. CS3 that worked without activation). But have I now come to the end of the road and no longer be able to activate any, even CS6 on a new Windows (especially Windows 11) computer?

Adding to my post above: I managed to reactivate the Master Suite CS6 on the computer where I deactivated it (that installation wen to "trial mode", and when I signed in and activated, it now seems to work as it used to; but as mentioned, deactivation on the same computer, even if was said to be successful, does not decrease activation count and make the Master Suite available on a new computer.

Another addition: I also tried reinstalling the Master Suite CS6 from a download provided by Adobe on their serial number site (in hope that this version would be somehow different than the original DVD US version), but it was just the same: installation wen well, the serial number was accepted, but activation fails on a new computer. I tried this with just having the initial version installed, and having made all possible updates (updates can still be made fine with internal update routines)

(this is the ONLY support Adobe still offers for old programs)
When you can't properly deactivate a serial number
BE SURE TO ONLY ASK FOR ACTIVATION SUPPORT TO ADJUST YOUR ACTIVATION COUNT
You may need to PERSIST or TRY AGAIN to find a support agent with more experience

Thanks, this worked (and so much better I could have expected)!
