Visual studio Team Foundation Server 2012 RC installation error

I am trying to install Team Foundation Server 2012 RC on a server which had a Team Foundation Server 2011 installed.
I am using Windows Server 2008Â R2Â Enterprise (64-bit). I am getting the following error during installation.
Can someone please explain why am I having this problem?
Thanks in advance.

Error :Â TF400534Â : Package (tfs_servercoreres_x64) caching failed with the following status :Â 0x80092009.
