I am installing Adobe Indesign CS5 onto a new computer. Her previous computer has CS5.5 installed. All the created documents are erroring out with plugin errors. How can I get this new computer upgrade to the CS5.5? How can I find the serial number on the older computer?

Moving the discussion to InDesign for further clarification on upgrading plugins as per the screenshot.
When CS5.5 is isntalled the plugin errors should disappear. There is no other plugin upgrade.
