Can I reuse the downloaded files from the VS2010 web installer

I installed VS2010 pro using the web installer, but now need to install it on another machine. As this new install will require the same features as my current install, is it possible to reuse the files 开发者_Python百科already downloaded? And if so, how is this achieved?

On my machine, the setup uses files from

C:\Documents and Settings\<username>\Local settings\Temp\30319.01\1033\VS_VSTD

but I don't yet know how to reuse them, or if that directory is the result of unpacking files from somewhere else.

I used filemon to see from where the setup was reading and writing.
