Err Msg: Msworks Caused an Exception 10H in Module Msworks.exe

When you perform one of the following actions:

• You click Create It in a spreadsheet or database task wizard in Works 4.x or later.
• You create a function that divides by zero in a database or spreadsheet in Works 4.x or later.
• You open a spreadsheet file in Works 4.x or later.
• You start Money 4.0.
• You try to open a different .mny file in Money 4.0.

You may receive an error message similar to one of the following error messages: You may also see blue sceens with errors in OE:O16F:BFF8E64B and 0E:0028:CC58565.

This behavior can occur if any of the following conditions is true:

• The driver for the printer is corrupted, or a beta version or an outdated version of the driver is installed on your computer.
  
  NOTE: If you are running Microsoft Works 2000 or later, an outdated printer driver is probably the cause of this behavior.
• The TEMP environment variable may point to an invalid folder.
• The math coprocessor installed in your computer is damaged.
• An exception error in Works 4.0 isn't handled correctly by the program.
• The issue can occur if you get a new printer and install an old version of that printer driver.

When Works asks the math coprocessor for the result of an Exception error, the printer driver may interrupt the math coprocessor call and return the Exception error back to the program instead of the result of the Exception error.

To resolve this issue, download and install the newest printer driver from your printer manufacturer. If you have completed this procedure and the procedure does not resolve the issue, restore the original printer driver from the Microsoft Windows CD-ROM or installation disks.

If the issue continues to occur, or if no driver for your printer is available on the Windows CD-ROM or installation disks, contact your hardware manufacturer to inquire about how to obtain and install the latest version of the driver for your printer.

For information about how to contact your hardware manufacturer, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base: If the issue continues to occur, or if the latest version of the printer driver for your printer is already installed on your computer, configure your printer to emulate a different printer. For information about how to do this, see your printer manual, or contact your hardware manufacturer.

If the issue continues to occur, verify that the TEMP environment variable points to a valid folder. To do this:

1. Click Start, point to Programs, and then click MS-DOS Prompt.
2. At the command prompt, type the following line, and then press ENTER:
   set
3. Note the folder specified on the TEMP= line.
4. If the folder is located on a different hard disk, type the following line, and then press ENTER:
   drive:
   where drive is the drive letter of the hard disk on which the TEMP folder is located.
5. At the command prompt, type the following line, and then press ENTER:
   cd\temp
   where temp is the path you noted on the TEMP=line in step 3.
6. If you receive an "Invalid directory" error message, type the following line at the command prompt, and then press ENTER:
   md temp
   If you do not receive an error message, type the following line at the command prompt, and then press ENTER:
   del *.tmp
7. At the command prompt, type the following line, and then press ENTER:
   exit

If the issue continues to occur, you may be able to work around this issue by turning off the math coprocessor. To do this:

1. Right-click the My Computer icon on the desktop, and then click Properties.
2. Click the Device Manager tab, and then click View devices by type.
3. Click the PLUS SIGN (+) next to System devices to expand the branch.
4. Under the System devices branch, click Numeric data processor, and then click Properties.
5. Click the Settings tab.
6. Click Never use the numeric data processor, and then click OK.
7. If you are prompted to restart the computer, click Yes.
   
   If you are not prompted to restart the computer, click OK, close Control Panel, and then restart the computer.

Microsoft has confirmed that this is a problem in Works for Windows version 4.0.
This problem was corrected in Works 4.0a.
