Re: Fireworks is asking for serial number [Branched & moved from 2017 topic about CS6]

No need for the Muse workaround, try the options below, if the first option doesn't work, the second should. Tested on Windows 10 and Windows 11.

1) Launch the Creative Cloud app

2) From your  profile icon (top right) click sign out

3) Then, Select file => Exit Creative Cloud (top left) to exit the Creative Cloud app

4) Now launch Fireworks, you will be prompted to login with your Adobe sign in details, do so

5) If you see a 'license this software' button click it, that should do the job.

*If the above does not work try this:

1) Uninstall Fireworks from your machine

2) Rename the following folder: C:\Program Files (x86)\Common Files\Adobe\OOBE to OOBE_BK

3) Download an offline Fireworks installer from here (these are official Adobe installers), be sure to visit this page first and sign in with your Adobe login to set an Adobe cookie, otherwise the download will not work.

4) Now install Fireworks with the offline installer you downloaded

5) Make sure you turn off automatic updates in the Creative Cloud app (in preferences=>apps) afterwards, otherwise it will update Fireworks and you may get the same issue again.

6) See if Fireworks will now launch, if presented with a 'license this software' button click it.

Fireworks is no more supported.The product is eol for quite a long time now. If you get it running, it's ok, if not, you are on your own. If you have a CC subscription, Fireworks is still part of the unsupported old programs. That's it.

Creative Cloud apps DO NOT use serial numbers.  They are activated with your Creative Cloud ID and password. 

1. Open CC Desktop App.
2. Click your Avatar (top right image) > Preferences > General tab > Settings. Select "Always keep Creative Cloud up to date."
3. Click on your Avatar again.
4. Sign-out of Creative Cloud.
5. Close all apps.
6. Restart your computer.
7. Open CC Desktop app.
8. Click your Avatar.
9. Sign-in with your paid ID and password.

Failing that, several users have found that installing Muse from Creative Cloud Desktop app allows access to legacy Fireworks.  I don't know why it works but having Muse installed appears to get passed the serial number prompt.

Once FW is running again, be sure to prepare an exit strategy to other graphics software by exporting your layered PNG files to PSD or TIF files.  There is no way to predict how much longer FW will keep working.  It was discontinued 12 years ago. 

Good luck! 🙂
