Can I install multiple versions of Matlab concurrently on a Windows 2008 R2 HPC Cluster

Hi, I currently have Matlab 2011a installed on all my Win 2008 R2 HPC Cluster nodes. I have not upgraded my clients to 2012a yet as it does not interact with the HPC cluster due to it having 2011a on the nodes. My question is - Can I install multiple versions of Matlab on the HPC Cluster nodes concurrently? This ability would allow flexibility in migrating my clients to newer versions of Matlab.

Thanks Pat
