DOCUMENT:Q146465 08-AUG-2001 [crossnet] TITLE :Err Msg: Setup Cannot Run In a 386 Enhanced Mode Windows... PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER:WINDOWS:95; winnt:3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.51 - Microsoft Windows NT Server version 3.51 - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== When you attempt to install Windows NT 3.51 on a Windows 95 computer with the "WINNT /B/W" (without quotes) command, the following error message appears: Setup cannot run in a 386 Enhanced Mode Windows MS-DOS Command Prompt. Exit Windows and run Setup again. Setup cannot continue. Press ENTER to exit. CAUSE ===== This problem occurs if there is no space between the /B and /W switches for WINNT.EXE. RESOLUTION ========== To correct this problem, type the following at the command line: WINNT /B /W MORE INFORMATION ================ The /W switch allows WINNT.EXE to run in Windows 95. You can use this switch with other WINNT.EXE switches. For example, if you want to create boot floppy disks for CD-ROM or floppy-based Windows NT installation, you can type the following at the command line: WINNT /OX /W "WINNT /W" allows you to install Windows NT from within Windows, bypassing the drive locking and enhanced driver issues involved with a Microsoft Windows install. Again, this bypasses many of the Windows NT install safety features and is not recommended. When you type "WINNT /?" (without the quotation marks) at the command line, the /W switch is not listed. For more information on the /W switch, please see SETUP.TXT on the Windows NT Server or Workstation 3.51 compact disc. For more information, regarding the /w switch and Windows NT 4.0 please refer to the following article in the Microsoft Knowledge Base: Q147012 Activating /W Switch to Prevent Rebooting in WinNT Additional query words: prodnt win95 ====================================================================== Keywords : Technology : kbWinNTsearch kbWinNTWsearch kbWinNT351search kbWinNTW351search kbWinNTW351 kbWinNTSsearch kbWinNTS351 kbWinNTS351search kbWin95search kbZNotKeyword3 Version : WINDOWS:95; winnt:3.51 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
