Virtualization

Hi Everyone
I virtualized office 2007 using app-v sp-1 sequencer . We have office 2003 natively installed on all the machines . Now we are planinning to deploy office 2007 virtualized on all the machines. Our company needs office 2003 as the standard one.

The problem I am facing is I installed office 2003 natively on the machine and after that I installed the virtual office 2007 in stand alone mode . When I try to open a .xls or .ppt the virtual package is getting launched and the file is getting launched by office 2007 .During sequencing I deleted all the file type association related to office 2003 . Any help on this would be appreciated.
