Installing Lightroom 6

Hello, 

I had purchased Lightroom 4 and 6 and had them both installed on my old computer. I have serial numbers for both. 

I just bought a new laptop (Windows) and I see the Lightroom 4 icon on my desktop. I clicked a setup file for Lightroom 6, it asked me to enter both serial numbers, and it installed the icon on my desktop. 

When I click on it, I get the message “ Adobe Application Manager, required to start your trial, is missing or damaged. Please download a new copy of Adobe Application Manager from http://www.adobe.com/go/applicationmanager”

I know Application Manager has now been replaced by the Adobe Creative Cloud. 

How can I get Lightroom 6 to open on my laptop so I can see my photos?

Thank you
