Application Error (100) 1000

I have next error message in the Event Log on a Windows Server 2008 computer with Excel 2000 installed:

Source Application Error

Category: (100)

ID: 1000

Faulting application EXCEL.EXE, version, module 36f43422, version EXCEL.EXE, address 0x9.0.0.2719.

What's the problem?




Step 1 - Install Updates

Go to, click on "Check for Updates", and follow the instructions.

Step 2 - Repair the Excel Installation

This option is only available in Excel 2000 and later. To repair the Excel installation, start Excel and choose the menu command Help->Detect and Repair. The product CD may be required.

Step 3 - Remove/Reset the Tool Bar Configuration File

Reset the toolbar settings file by deleting the Tool Bar Configuration File while Excel is not running. This file is usually located in the folder

C:\Documents and Settings\Your Login Name\Application Data\Microsoft\Excel and is named "Excel *.xlb".

Step 4 - Reset the Registry Entries

Instruct Excel to reset the Excel registry entries. Do this by opening the Start menu and selecting Run. Enter "Excel.exe /RegServer" and click OK.

Step 5 - Clear the Option Settings

Run RegEdit (Start->Run, enter regedit, and press ENTER) and navigate to HKEY_CURRENT_USER\Software\Microsoft\x.0\Options where x is 9 for Excel 2000, 10 for Excel 2002 or XP, and 11 for Excel 2003. Delete all entries except for "(Default)".
