Crystal Reports 2008 and 2013 on the same machine?

Can Crystal Reports 2008 and 2013 coexist peacefully on the same machine?

One of my users has CR 2008 installed on his workstation in order to support a vendor application that has embedded CR 2008 reports.  Can he also have CR 2013 installed on that same machine?

We have BusinessObjects environment is 4.1 SP01 Patch 2.

Thanks,

Noel
