Update: several users confirm that Activation Code can now be created and the procedure works.

Ive followed all these instructions over and over

Log into the service center on vegascreativesoftware.com
Click "create activation code"
Type in the serial number for the SCS era software
Type in the computer ID provided by the SCS era software when prompted
Copy and paste the activation code provided into the field in the SCS era app prompt. 

Ive used my new computer ID, my old computer ID and ive even ade up a few just for the fun of it and it gives me the exact same Activation code (That it wont accept) every single time

B66G0-TB1YG-775D4-EZW9Y

It tells me i typed it wrong or i missed a letter or the caps lock is on ....it doesn't matter what i do it simply wont accept it.

new to forum, attempting to resurrect licensed v 9.0e from a failing legacy Sony VAIO, and tried in vain to register (screen says license was accepted), but failing to generate an activation code (says not registered).

In trying to re-register Sony Sound Forge 9 I followed all the steps including the creation of a new authentication (activation?) code (the 3rd on he list of steps to take. . I saved it to my Documents folder. Then I double-clicked the file and still the Sony registration site does not open and I cannot go any further. What to do?

Thanks for clearing this up! I was stuck trying to figure out why the old Sony activation servers weren’t responding anymore. The offline method looks straightforward enough, glad there’s still a way to keep older versions running without having to give them up completely.

I have tried to follow these instructions, but I get a message that my product is already registered, so it will not allow me to proceed any further. It gives me a link to check the registration, but all that does is confirm that it has been registered. I had originally installed the software on a laptop that is old and being replaced, so I am trying to install to a different computer. However, it won't allow me to proceed.

@Steven-Drennon  ... this may be another issue related to the number of activations allowed with Sony-era software aand addressed in point 9 in https://www.vegascreativesoftware.info/us/forum/vegas-pro-faqs-and-troubleshooting-guides--104787/

• Older versions of Vegas Pro than 14.0 are licensed under a system (as previously used by Sony) which permits use on multiple computers by one user; after an unspecified number of installations on different or updated PCs you may need to contact support to reset your "installation count".

There's a Support link at the bottom of the following Support webpage found in the header of the forum:

BTW, I had this happen once or twice back in the Sony-era.

I am having the same issue, also with Sound Forge Audio 9.0, have registered the S/N multiple times, but when trying to activate----after clicking Proceed----the website keeps saying product is not registered.

@Steve-Kessler Presumably you've looked at all the links in this thread. If nothing works suggest you contact Vegas Support.

Have sent an email to Vegas Support. Crossing my fingers....

(Definitely looked at all the links in this thread.) I'm caught in a loop of the Vegas 9 license being recognized, but then activation code sequence says product not registered. Support ticket gave me the pat instructions and never did answer head-on my problem (even after I sent screenshots), and then closed the ticket! I'm agreeing with an earlier poster that it seems I am being herded to buy a new version.

Finally heard back from MAGIX Support, and as @Jeff-Lewis suspected, yes we are being herded to buy a new version:

"Unfortunately, Sony has turned off the servers for the old Sony VEGAS and SOUND FORGE products on 01/08/2025, so that registration is now no longer possible. As this was a decision made by Sony, 
we are unfortunately unable to assist you with this problem.

However, you can upgrade to the latest version of the software with the old serial number. As you own a previous version, you can purchase the latest version at a discounted price. 
Further information as well as a free trial version can be found here:"

@Steve-Kessler Sadly this appears to indicate that there are communication problems within Magix as my understanding is that while the old servers have been turned off users are not being herded to buy a newer version. This thread is about how old SCS products can be activated.

Steve, Did you contact MAGIX support or VEGAS support? I understand there is a difference.

I contacted MAGIX support and that above is their reply.

I have the same problem as Steve Drennon with the loop. "I have tried to follow these instructions, but I get a message that my product is already registered, so it will not allow me to proceed any further. It gives me a link to check the registration, but all that does is confirm that it has been registered." I have the program on an HP laptop and have been using it for years. I've had to re-register/activate it in the past many times but it worked every time. I understand that the old registration process is caput now but the program stopped working again for no reason and I'm stuck.
