Some Retail Version DLL and EXE Files Not Installed in Windows

• Microsoft Visual C++ for Windows, versions 1.5, 1.51, 1.52, 1.52b, 1.52c

SUMMARY

When Debug Kernel under Tools is chosen in Custom Installation, you may see the following message:

   "Some files in the retail version of Windows were not installed. Install
   retail versions of KRNL386.EXE, KRNL286.EXE, GDI.EXE, USER.EXE, and
   MMSYSTEM.DLL in 'C:\MSVC\NODEBUG' before trying to switch from the
   debugging to the retail version of Windows using D2N.BAT."

MORE INFORMATION

The reason for this message is that setup has not copied the KRNL286.EXE file in the C:\MSVC\NODEBUG directory.

KRNL286.EXE should be used when debugging applications in Standard Mode and KRNL386.EXE should be used when debugging in Enhanced Mode.
