Updating Office 2011 to Obtain Retina Update

I purchased a new computer (2017 MacBook Pro) and installed my CD copy of Microsoft Office 2011 on it. However, after installation I learned that Microsoft has abandoned Office 2011 for Mac and is no longer allowing people to download the retina update they released after the initial 2011 CD's were burned. The applications run fine on my laptop; however, the app's text and features are all blurry running on my modern Retina 2017 MacBook Pro.

I have Office 2011 running on several other Mac's in my house, that all received the latest retina updates (and others) from MS until these stopped in late 2017.

Hence my question: is it possible, and if so how, to transfer the system files from these properly running "Retina updated" MS Office 2011 files from these other Macs and get them to run with the retina update on my new 2017 MacBook Pro?

Or alternatively, is there any other way to find the necessary files to get MS Office 2011 running properly with the retina update on my new laptop?
