Problems with 16-Bit Programs After Installing SP2
Submitted 7/24/02
After the installation of Service Pack 2, (SP2), for Windows 2000 the operating system ceased to execute 16-bit programs. This was due to a program compatibility feature within VDM, (Windows NT Virtual Dos Machine), that prevented the operation of 16-bit applications, and generated the following error code
<Program> caused a general Protection Fault in module KRNL386.EXE at 0001:6382 Choose close. <Program> will close
The resolution is …
- Start – Run – REGEDIT
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\SessionManager\AppCompatability\
- Delete the NTVDM.EXE subkey
- Click YES for confirmation
- Restart your computer
