Windows NT 4.0 SP4 Setup Does Not Update Winprint.dll

After you apply Windows NT 4.0 Service Pack 4, you notice that Winprint.dll, located in the System32\Spool\Prtprocs\W32<platform> folder, is not updated although the file is included in Service Pack 4.

Update.exe looks for Winprint.dll in the wrong folder.

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
