You may experience problems running MS-DOS-based programs that rancorrectly in an MS-DOS session in an earlier version of Windows.
The MS-DOS-based program may be using a Windows 3.x program informationfile (PIF) instead of a newer PIF optimized for Windows.
Rename the PIF that is located in the same folder as the MS-DOS-basedprogram. Then, try to run the MS-DOS-based program by double-clicking theprogram's executable file in Windows Explorer or My Computer.
If the program still does not run correctly, refer to the program'sdocumentation to determine the optimal settings for the program, and thenfollow these steps:
Use the right mouse button to click the program's executable file, and then click Properties on the menu that appears.
In the program's properties, enter any specific PIF configuration information suggested in the program's documentation.
When you are done entering information, click OK.
These steps create a new PIF in the program's folder. The new PIF will bereferenced when you start the program.
If the program still does not run correctly, you may want to contact theprogram's manufacturer for additional information, or try running theprogram in MS-DOS mode.
For information about running programs in MS-DOS mode, please see thefollowing article in the Microsoft Knowledge Base:

When you start an MS-DOS-based program in a folder that contains a PIF forthat program, Windows uses that PIF to obtain configuration informationfor the MS-DOS session.
If there is no PIF in the program's folder, Windows queries the Apps.inffile to determine whether an entry for that program exists. If so, Windowsuses the settings in the Apps.inf file to create a new PIF in theprogram's folder.
