This article was previously published under Q189670



SYMPTOMS
When you attempt to install Windows 98, you may receive the following error message:

Windows 98 requires a computer with a math coprocessor.

You may receive this error message even though your computer contains a math coprocessor.



CAUSE
This behavior can occur if math coprocessor support is disabled in Device Manager.



RESOLUTION
To resolve this behavior, follow these steps:


 * 1) Click Start, point to Settings, and then click Control Panel.
 * 2) Double-click System.
 * 3) On the Device Manager tab, double-click the System Devices branch to expand it.
 * 4) Click Numeric Data Processor, and then click Properties.
 * 5) On the Settings tab, click the "Always use the numeric data processor" check box to select it, and then click OK.
 * 6) When you are prompted to restart your computer, do so.

To work around this behavior, use the setup /nm command. The /nm switch bypasses the minimum hardware requirement test. This tests for a minimum of a 486/66DX central- processing unit (CPU) and 16 megabytes (MB) of memory and the presence of a math coprocessor.
