SYMPTOMS
When you start Excel 2000, the program abruptly quits and you receive the following
error message:

The system is dangerously low on resources.
CAUSE
This issue may occur if the Excel toolbar file (Excel.xlb) is damaged. The Excel
toolbar file stores information about menu changes and about any custom menus that
you may have created.
RESOLUTION
To determine whether the Excel.xlb file is at fault, first start Excel 2000 in Safe
mode. Safe mode bypasses the Excel toolbar file, any startup or shutdown macros that
you may have configured, and any files in the XLStart folder. To do this, follow
these steps:
Click Start, and then click Run.
Click Browse, and then navigate to Excel.exe in the following location:
C:\Program Files\Microsoft Office\Office

In the Open box, add a /s switch to the end of the file path, as follows:
"C:\Program Files\Microsoft Office\Office\Excel.exe" /s

Click OK.
If you still receive the error message, the problem does not reside in the Excel.xlb
file. The error may reside in the Microsoft Windows operating system, in which case
you will want to contact Microsoft Windows Product Support for help. For a complete
list of Microsoft Product Support Services phone numbers and information about support
costs, visit the following Microsoft Web site:

If you do not still receive the error message, the Excel toolbar file may be damaged.
Use Windows Explorer to locate the Excel toolbar file, located in the C:\Windows\Application
Data\Microsoft\Excel folder and named:
Excel.xlb, if your computer is not connected to a network or is not set up with a
logon prompt.
