Is there a way to programmatically tell if a machine meets the requirements
to install .Net 3?

Hi sonny,

The requirements of the .NET Framework 3.0 are supported operating systems:
Longhorn; Server 2003 SP1; Vista and XP SP 2(http://www.microsoft.com/downloads/details.aspx?FamilyId=10CC340B-F857-4A14-83F5
-25634C3BF043&displaylang=en).

What you need to do is to use e.g. Environment.OSVersion to determine current
system reqs.

Thx Alex,

I've looked into the Environment object. What seems to be missing is the
Service pack version. I can get the Major/Minor Os Version from the
registry, so determining Vista is pretty straight forward. What I haven't
figured out is how to determine what Service Pack is installed on XP without
doing some hokey parse. (ex: parsing the number from the CSDVersion
registry key and checking to see if its >= 2)

Hi sonny,

Either Environment.OSVersion.ServicePack or [kernel32.dll].GetVersionEx()

Thx again Alex.

I glanced over the OSVERSIONINFOEX too quickly. I see the info now.
