To resolve this issue, run Windows 95/98 Setup from within your current version of Windows. If you receive the same error message, rename the Aolndi.dll file in the Windows\System folder, and then run Setup from MS-DOS. To rename the Aolndi.dll file, follow these steps:

1.	Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode Command Prompt Only from the Startup menu. For Windows 98, restart your computer, press and hold down the CTRL key after your computer completes the Power On Self Test (POST), and then choose Safe Mode Command Prompt Only from the Startup menu.
2.	Type the following lines, pressing ENTER after each line: cd\windows\system ren aolndi.dll *.old where windows is the name of your Windows folder.
3.	Restart your computer, and then run Windows 98 Setup again.
