Outlook Performs Illegal Operation when clicked on

[Lowell Copeland]

Windows 98SE. When I click on Outlook icon on desk top, the program begins to open and then displays an error message which says, "This program has performed an illegal operation." When I click on the "Details" button, I get the following message. "Outlook caused an invalid page fault in module MSVCRT.DLL at 018f78010660

Registers: etc

I checked the Knowledge Base Article 264258 and tried to run Nfclean.exe, but nothing happened. I even made sure nfclean.exe was in directory Program Files/Microsoft Office/Office/1033

I still get the same error. Any ideas will be appreciated

Outlook caused an invalid page fault in module MSo9.dll at <memory address>


CAUSE

=====



The file Mso9.dll, common to all Microsoft Office 2000 programs, may be
damaged
or missing.



RESOLUTION

==========



To resolve this problem, rename both the Outcmd.dat and Mso9.dll files, and
then use Add/Remove Programs to repair Outlook.



To Rename the Outcmd.dat File

-----------------------------



1. Click Start, point to Find, and click Files or Folders.



2. In the Named box, type "Outcmd.dat" (without the quotation marks). Ensure
that the entire hard disk drive is being searched, click My

Computer in the Look In list. Select the Include Subfolders option, and
then
click Find Now.



3. Right-click the file, and then click Rename. Rename the file by changing
its
file name extension to ".old" (without the quotation marks), and then press
ENTER.



4. Close the Find Files dialog box.



To Rename the Mso9.dll file

---------------------------



1. Click Start, point to Find, and click Files or Folders.



2. In the Named box, type "Mso9.dll" (without the quotation marks). Ensure
that
the entire hard disk drive is being searched, click My Computer in the Look
In
list. Select the Include Subfolders option, and then click Find Now.



3. Right-click the file, and then click Rename. Rename the file by changing

file name extension to ".old" (without the quotation marks), and then press
ENTER.



4. Close the Find Files dialog box.



To Repair Outlook

-----------------



1. Click Start, point to Settings, and click Control Panel.



2. In Control Panel, double-click the Add/Remove Programs icon.



3. In the list of installed programs, click to select either Microsoft
Outlook
or Microsoft Office, depending on how you installed Outlook.



4. Click Add/Remove.



5. After setup begins, click Repair Office.



6. Click Repair errors in my Office 2000 installation, and then click
Finish.



The repair process may take several minutes while Office Setup repairs any
damaged or missing files. If you receive a prompt to restart your computer,
click Yes.
