I may be the slow guy in the room... .NET 3.5 installation includes Service Packs for .NET 2.0 SP1 and .NET 3.0 SP1, both of which replace previous versions. I checked with our IT team and we've apparently not installed 2.0 SP1 "yet". There's a concern of compatibility as previous upgrades from 1.0 caused some issues (before my time at this company). I've not personally experienced problems with these in the past and I've worked with .NET since beta versions of 1.0. If you'd like to do a quick check to see if .NET 2.0 SP1 is installed check out [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727\1033], "SP" should have a value of "00000001". I checked a machine without .NET 2.0 SP1 and then checked a machine with .NET 3.5 and this holds true.
