-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows versions 3.1, 3.11 
-------------------------------------------------------------------------------

SUMMARY
=======

Some object-linking-and-embedding (OLE) servers may provide a text file called
SETUP.REG, or a similarly-named file. This file contains information about the
particular server application and can be used to repair an application's entry
in the Windows REG.DAT file. This is necessary only if you think the entry is
incorrect or the REG.DAT file is corrupted.

MORE INFORMATION
================

The REG.DAT file is the registration database. The database is a source of
information about server applications in a binary format. Information in REG.DAT
includes:

1. Class name - This describes the type of information contained within an
   object.

2. The path to the server

3. Any verbs supported by the server - This includes actions the server can take
   on the object.

The information in REG.DAT is used when you open or print a file from File
Manager. This information is also used by applications that support OLE. The
registration database (REG.DAT) is set up and maintained by Windows and Windows
applications. It is located in the WINDOWS directory. This file should not be
moved or deleted. Doing so may result in loss of functionality in File Manager,
Program Manager, and applications that support OLE.

SETUP.REG is a text file that contains the same information as REG.DAT except its
format is ASCII instead of binary. SETUP.REG can be merged with an existing
REG.DAT file to repair or update an individual entry in the REG.DAT file. If
REG.DAT or OLESVR.DLL is damaged or corrupted you may get the following error
message.

   Failed to register server.

Sample SETUP.REG Entries for PaintBrush
---------------------------------------

Note: PaintBrush can only act as a server application.

   HKEY_CLASSES_ROOT\.bmp = PBrush
   HKEY_CLASSES_ROOT\.msp = PBrush
   HKEY_CLASSES_ROOT\.pcx = PBrush
   HKEY_CLASSES_ROOT\PBrush = Paintbrush Picture
   HKEY_CLASSES_ROOT\PBrush\shell\print\command = PBRUSH.EXE /P %1
   HKEY_CLASSES_ROOT\PBrush\shell\open\command = PBRUSH.EXE %1
   HKEY_CLASSES_ROOT\PBrush\protocol\StdFileEditing\verb\0 = Edit
   HKEY_CLASSES_ROOT\PBrush\protocol\StdFileEditing\server = PBRUSH.EXE

Steps to repair REG.DAT with an application's SETUP.REG file:

1. Open Program Manager. From the File menu, choose Run.

2. Type REGEDIT .

3. Choose the OK button.

4. From the File menu, choose Merge Registration File.

5. Select the .REG file that needs to be merged into the existing REG.DAT file.

The Merge Registration File command merges the selected registration (SETUP.REG)
file with the currently displayed database (REG.DAT). The merged information is
not written to the REG.DAT file until you choose the Save Changes command.
