The Search version of MSDN included with Visual FoxPro is the standard quarterly subscription release, which does not include a critical file VSHELP.dll required to enable functionality of the MSDN Search menu option. This update installs the VSHELP.dll file. If you previously installed Visual FoxPro 6.0 or Visual Studio 6.0, along with the MSDN help files, do not install this update. This issue applies only to the development version of Visual FoxPro and does not affect the Visual FoxPro runtime libraries..
