VS2008 on Windows 7 RTM with x64 compiler broken <p>I am having trouble getting x64 compilation to work on Windows 7 RTM (64-bit) with Visual Studio 2008 Professional (both with and without SP1). I have not installed the Windows 7 SDK, as <a href="http://blogs.msdn.com/windowssdk/archive/2009/06/15/installing-win-7-sdk-rc-and-vs2008-rtm-can-disable-vc-configuration-platform-choices.aspx" rel="nofollow noreferrer">Microsoft suggests might be the issue</a>. The problem is that there are no x64/64-bit choices in the Configuration Manager of Visual Studio. </p> <p>I do not have the "Microsoft Visual C++ Compilers 2008 Standard Edition" suggested in the link above installed on my computer. Any ideas what might fix this?</p> <p>I have checked that I have the x64 compiler and tools installed with Visual Studio.</p> <p><strong>Solution found</strong>: Uninstall VS completely and reinstall. Issue resolved after SP1 installed (again). Very strange.</p>
