KEYWORDS:

WARNING: Using Registry Editor incorrectly can cause
	 serious, system-wide problems that may require you to
	 reinstall Windows NT to correct them. Microsoft cannot
	 guarantee that any problems resulting from the use of
	 Registry Editor can be solved. Use this tool at your own
	 risk.

Summary:

You may receive a general protection (GP) fault when you run an OS/2-
based program if the OS/2 subsystem registry entry is corrupted.

To renew the registry entry, follow these steps:

1. Start Registration Information Editor (REGEDT32.EXE.)

2. From the HKEY_LOCAL_MACHINE window, select SOFTWARE\Microsoft.

3. Choose the OS/2 Subsystem for Windows NT, and press the DELETE key.

4. Shutdown your system, then restart Windows NT.

5. Start any OS/2-based application.

When you start an OS/2-based application, the OS/2 server rebuilds the
appropriate registry entries. The GP fault should no longer occur.
