Hi Thomas,

I (well my customers anyway) have run into this behavior on more than a few
occasions. When macros silently fail to execute, odds are the MSCORLIB.TLB
has somehow been unregistered on your system. This can be caused by someone
inadvertently including/deplioying MSCORLIB.TLB with their addin or other
project, and then subsquently unregistering it during an uninstall.

Below is the preliminary copy of a knowledge base article I wrote that
addresses this topic. In addition to MSCORLIB.TLB not being registered, it
may also be improperly registered. In some cases, we've seen some beta
software mess up the registry keys mentioned in the article below.

Let me know if neither of these suggestions fixes the problem for you.

Thanks,
Ed Dore [MSFT]

PRB: Macros may fail to execute in Visual Studio .Net.

Symptoms
=======

When attempting to execute (CTRL+P) or debug a macro, the macro fails to
execute
with no errors or warnings generated.

Cause
=====

This problem is known to occur when the MSCORLIB.TLB type library has
either failed
to register during install, or when inadvertently unregistered by some
other
application.

Resolution
==========

To fix this problem, you can use the REGTLIB.EXE utility to reregister the
MSCORLIB.TLB, as follows:

  From the Start.Run dialog, enter the following text, and then click OK.
     “<path1>\regtlib.exe” “<path2>\mscorlib.tlb”

  Where <path1> is the full path to the regtlib.exe utility on your
computer, and
<path2>
  is the full path to the most recent version of mscorlib.tlb on your
computer.

For example:

  “C:\Windows\System32\UrtTemp\regtlib.exe”
“C:\Windows\Microsoft.Net\Framework\v1.1.4322\mscorlib.tlb”

More Information
================

Most systems include a copy of the REGTLIB.EXE utility, but you may have to
search
your hard drive to locate it. For example, on some systems you may find a
copy in
the C:\Windows, and on others, it may be located in
C:\Windows\System32\URTTemp. If
this file doesn’t exist on your system, you can download and extract it
from the
latest Visual Studio 98 Service Pack, at the following website:

  <http://msdn.microsoft.com/vstudio/sp/vs6sp3/default.asp>

Likewise, you may need to search your hard drive for the latest version of
mscorlib.tlb. This will typically be found under the
C:\Windows\Microsoft.Net\Framework directory.

The REGTLIB.EXE utility is used as follows:

  Regtlib [-q][-h] -o(odl file) | <typelib, olb, exe or dll filename(s)>

  Where:
     -q quiet mode (no messages)
     -o read an ODL file and use importlib() statements for typelibs to
register
     -h<path> Directory for help file of typelib
     -? Display usage help

Status
======

Microsoft has confirmed that this is a bug in the Microsoft Products that
are
listed at the beginning of this article.

The following is what this article should read like: Note, we added a 2nd
step to
the resolution section, as we've seen instances where running regtlib.exe
doesn't
correct a bad path to mscorlib.tlb in the registry keys mentioned below.

to execute with no errors or warnings.

Cause Section
=============

This problem is known to occur when the MSCORLIB.TLB type library has

some other application.

Resolution Section
==================

To fix this problem, use the REGTLIB.EXE utility to reregister the
MSCORLIB.TLB as
follows:

  From the Start.Run dialog, enter the following text, and then click OK.
  "<path1>\regtlib.exe" "<path2>\mscorlib.tlb"

  Where <path1> is the full path to the regtlib.exe utility on your
computer.
  Where <path2> is the full path to the most recent mscorlib.tlb on your
computer.

Note, on some systems, this file may not be present on the machine. You can
extract
a copy of REGTLIB.EXE from the OAINST.CAB file.

  For Visual Studio .Net 2002, the OAINST.CAB file is located in the IE60
  directory of the Windows Component Update CD.

  For Visual Studio .Net 2003, you will find a copy of OAINST.CAB in the
  IE60SP1 directory of the Prerequisites CD.

If macro execution continues to fail after reregistering the MSCORLIB.TLB
type
library, use the regedit utility to ensure that the following registry
key(s)
contains the full path to the corresponding mscrolib.tlb file.
 
 
HKEY_CLASSES_ROOT\TypeLib\{BED7F4EA-1A96-11D2-8F08-00A0C9A6186D\1.0\0\win32
  (set to valid full path for v1.0.3705\mscorlib.tlb)

 
HKEY_CLASSES_ROOT\TypeLib\{BED7F4EA-1A96-11D2-8F08-00A0C9A6186D\1.a\0\win32
  (set to valid full path for v1.1.4322\mscorlib.tlb)

Hi all - I finally got it to work by uninstalling and re-installing the
.NET framework SDK version 1.1. Registing the .TLB file did not seem to
help/Registry entries did not help. Thanks for all the reponses.
