Class not registered...

Louie Warren

For some time now, I have received the following pop-up
when starting Excel...

CLASS NOT REGISTERED. LOOKING FOR OBJECT WITH CLSID:
(AC9F2F90-E877-11CE-9F68-00AA00574A4F)

I found some site on the net that said all I had to do was
do the repair/reinstall from the setup CD and it would fix
it. I have done that; it didn't work. I have completely
removed and reinstalled Office 2000; it didn't work. What
is this and how can I fix it?

Thanx.

Hi Louie,

The KB article shown below describes this problem and how to fix it.
It's referring to Excel 97, but the problem and solution are exactly the
same for Excel 2000.

When you attempt to insert a UserForm while you are in the Microsoft Visual
Basic Editor in one the products listed at the beginning of this article, or
when you attempt to open a document that contains a UserForm, you may
receive the following error message:

Class not registered.
Looking for object with CLSID:{AC9F2F90-E877-11CE-9F68-00AA00574A4F}

or

Class not registered.

The Help topic does not exist. Contact your application vendor for an
updated Help file (129)

The dialog box is dismissed when you click OK.

CAUSE
=====

This problem may be caused by a missing or incorrect Microsoft Windows
registry entry for the Dynamic Link Library Fm20.dll. The proper
registration of this file is required when you work with UserForms and form
controls in Microsoft Excel 97.

RESOLUTION
==========

To resolve this problem, register Fm20.dll. You must have Regsvr32.exe to
register Fm20.dll. If you do not have Regsvr32.exe you can download the
file. For additional information, please see the following article in the
Microsoft Knowledge Base:

Q161983 Regsv32a.exe Available in Download Center

Registering Fm20.dll
--------------------

To Register Fm20.dll, follow these steps:

1. Use Microsoft Windows Explorer to locate the Fm20.dll file in the
Windows\System folder or in the Winnt\system32 folder (under Microsoft
Windows NT). If the file is not present, copy it from the OS\System folder
on the Microsoft Office 97 compact disc to the appropriate location.

2. Close all open programs.

3. Click Start on the Windows taskbar, click Run, and then type the
following:

" Regsvr32.exe fm20.dll" (without the quotation marks)

4. Click OK. The following message should appear:

DllRegisterServer in c:\windows\system\fm20.dll succeeded.

The file Fm20.dll should be registered correctly.

STATUS
======

Microsoft is researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
