Serial number [edited-kglad] deactivating?

Question

I bought a cs6 several years ago and installed it on my old computer... few years later i installed it on a new laptop without deactivating the old computer. Now i have a new computer and wanted to install it again...
now i got the Massage, that the serial Number is already in use two times.
 
I should deactivate it on one of the other devices... on my laptop i cannot remove it, still need it.... and the old computer doesnt excist anymore.
can i See a list of activated devices, location of IP or else anywhere? 
Is there any possibility for a coersive-deactivating of the old computer?

When you can't properly deactivate a serial number
(this is the ONLY support Adobe still offers for old programs)
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

Be sure to remain signed in with your Adobe ID before accessing the link below
Do be aware that wait times are sometimes long before an agent responds
.
You MUST make sure that your browser does NOT block ads, scripts, or pop-ups
You MUST also allow 'cookies' in your web browser for the link to work
This will NOT work if you are using a VPN
.
This link will go directly to the chat option

Type "Agent" in the chat box to bypass the chatbot and be connected to a person
-Meaning type in the word Agent in the lower right, without the quote " " marks
or
X (aka Twitter) tweet @AdobeCare
.
Adobe does NOT do support by email, so beware of answering anyone who sends you a private message

if you purchased from or registered with adobe (and remember your adobe id), you can deactivate from https://account.adobe.com

otherwise, following @John T Smith's advice will deactivate ALL current activations.
