Crystal reports error on new server

I'm trying to run a web application that uses crystal reports on a new web server. I recently installed Crystal on the new server and migrated the website over to it.

When I try to generate the reports on the website I get the following error: An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly. Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required.

I have search for a runtime file and found one off of the site for Crystal Reports 2008, however, after installing, the error is still happening.

How do I know what to install and where to find it?
