Serial number not working for CS5 InDesign on Mac OS X High Sierra

[tkhawam]

I have CS6 without InDesign, and CS5 original full version CD with InDesign and were working on my Mac OS X Yosemite, I updated my iMac to High Sierra 10.13.6. I installed CS6 which doesn't have InDesign and working fine with the serial number. I installed CS5 InDesign from Creative Suite 5 Design Premium CD which has it's own serial number and shows a green check mark for the serial number during installation, but when I launch InDesign it ask me for serial number and display this "This serial number is not valid for this product"

Please let me know if you can check and validate the serial number.

Thank you,

Tony
