Windows 98 Setup Stops Responding While Trying to Play a Sound

When you try to install Windows 98, your computer may stop responding (hang). Also, if you run Setup again, Setup may not play sounds during the setup process.

This behavior can occur if Setup is unable to play a test sound file. If Setup is unable to play a test sound file, it does not play sounds during subsequent Setup attempts.

This behavior may be related to sound problems present before you ran Setup.

Windows 98 Setup uses the first sound as a test. If the test causes your computer to stop responding (hang), the following registry key prevents Setup from playing sounds the next time you run Setup:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\NoMusic
