<p>I'm running Windows Server 2008 64-bit "workstation" and would like to get <a href="http://msdn.microsoft.com/en-us/library/ms164699%28v=vs.80%29.aspx" rel="nofollow noreferrer">corflags.exe</a>. Which SDK do I need to download? </p>

<p>I know about <a href="http://www.microsoft.com/downloads/details.aspx?FamilyId=1AEF6FCE-6E06-4B66-AFE4-9AAD3C835D3D&amp;displaylang=en#Overview" rel="nofollow noreferrer">.NET Framework 2.0 Software Development Kit (SDK) (x64)</a> and <a href="http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&amp;displaylang=en" rel="nofollow noreferrer">Windows SDK for Windows Server 2008 and .NET Framework 3.5</a> but I was hoping to find something smaller as these are quite large downloads.</p>

<p>Also the note about 2.0 SDK seems to suggest to download the 3.5 one, should I follow that?</p>

If you install the .NET framework (you should already have it), it'll be at C:\Program Files (x86)\Microsoft.NET\SDK\v2.0\Bin\corflags.exe
Come to think of it, you may need to install 
the Microsoft .NET 2.0 SDK from
.NET Framework 2.0 Software Development Kit (SDK) (x64)
-- check for that file first.
