Rhino error when set up reaches 50%

I am trying to install Rhino but I am getting an error when the setup reaches 50%. "Error 1311. Source file not found:
C:Docume~1userlocals~1temprar$Dl10.5063Rhino4_setup7.cab. Verify that the file exists and that you can access it." How can this issue be resolved? Can I set it up without getting this error? Your help will be appreciated.
