I can't seem to find where to download the SDK for 2007 vol 2 for CLR2.0 (both Winforms and ASP.Net). The archived downloads page does not have it.
If you had a registered license when 2007.2 came out, you should be able to login and download it in the My Keys & Downloads area. We don't currently offer that version for trial, but if you have specific needs around it, you may be able to contact sales to get it.
