Hi

Have above complete with CD and code. After updating from Windows 10 to 11, I cannot get my version activated. The servers are no longer online. What to do?

Thanks for your advice. But when typin serial, I get message: This serial not valid for this product. Both CD and serial are original.

Do you have an upgrade version? Or EDU?

CS5 is old and no longer supported. Look through the forums, you aren't the first one to have problems installing on a new computer.

@Erling7913 most likely you have an upgrade CD not the full installation which would require the original serial number that you are upgrading from.

your serial number and install file do not match.  this not caused by your os.

=============

15-year-old legacy products were never intended to run on modern devices. Technology has changed too much. 

Best advice, replace legacy apps with newer ones built to run on Win11 machines.
