Unable to deactive CS5

Hi.

I just plan on wipe out the hard drive from my old laptop (Sony VAIO EA37) to upgrade to Windows 10 (from Windows 7 Home Premium), then processed to deactivate all software license. But then I have trouble deactivate my Adobe Creative Suite 5 Web Premium, as well as Acrobat 9 Pro.

Following the troubleshooting guide, I try to update the Adobe Application Manager, make sure all application is update to date ( your application are all up-to-dates as checked: less than a minutes ago. then open Adobe Photoshop 5 extended -> Help -> Deactivate, bring up the Deactivation Dialog. Now, either Suspend Activation, or Deactivate Permanently, lead to "Deactivation was not successful. please try again" with Error Code: 194:6‌.

Adobe Acrobat 9 Pro also experience exact same problem ("Deactivation denied" with exactly same error code)

After looked up all troubleshooting from CS6 to CS5, I contact Customer Service chat (if you need to case number, I could provide), then the staff point me out here (but she/he said I'm fine to uninstall the application first then ask for support here - I'm in the middle of system upgrade process, mind you.).

Currently I have 2 computer installed the CS5 Web Premium - one for my desktop (still installed, although I've experience update issue couple months ago without resolution, I just ignore that), and one for my laptop (which I want to uninstalled first before doing a clean Windows 10 upgrade.).

Could you help me resolve this issue?
