SYMPTOMS
If one of your Microsoft Transaction Server (MTS) components does not
register a ProgID, then the MTS package export feature generates a bad
client installation EXE. Any client installation EXE file generated for
that component deletes large portions of the registry when it is run. After
running such a client installation EXE you must reinstall the operating
system.
CAUSE
The MTS client installation EXE expects the components to register a
ProgID.
RESOLUTION
The two workarounds for this behavior are:
- Make sure that all components in your MTS packages register a ProgID.
-or-
- Do not use client installation executables to configure clients of those
components.
You also need to consider the following:
- Visual Basic (VB) components always register ProgID's.
- Microsoft Foundation Class (MFC) components register ProgID's by
default. If, however, you change the code around enough, you can cause
them to stop registering ProgID's.
- The Active Template Library (ATL) object wizard creates components
that generate ProgID's. Again, if you change the code around you can
cause these objects to stop registering ProgID's.
Conversely, many technologies require you to add code by hand to your
component to register its ProgID. This code should be added to the
implementation of the DllRegisterServer API function. In particular, the
following technologies do not automatically generate such code:
- ATL, when generated without the aid of the ATL Object Wizard.
- Visual J++
- C or C++ components generated without the aid of ATL or MFC.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This bug has been fixed in Microsoft Windows NT 4.0 Service Pack 4 (SP4).
MORE INFORMATION
Steps to Reproduce Behavior
WARNING: REPRODUCTION OF THIS BUG REQUIRES A REGISTRY RESTORATION OR
COMPLETE SYSTEM RE-INSTALLATION.
Create a component without a ProgID. Install or import the component into
an MTS package. Now export the package. This produces a .pak file (the
server-side deployable form of the package) in the directory you specified,
as well as an EXE file in the clients directory under that directory. This
EXE file is the client-side remote application setup program, and it
installs the necessary components for a client to talk to a server.
Now that you have produced the faulty client installation executable, run
the EXE. The result is that the HKEY_CLASSES_ROOT tree in the registry will
be deleted. This in turn causes every application using COM to stop
functioning.
