SYMPTOMS
========

When you start your computer, you encounter the following error message:

  Load needed DLLs for HAL

CAUSE
=====

This error can be caused if you uninstall Diskeeper for Windows NT 3.5x after
you upgrade Windows NT 3.5x to Windows NT 4.0.

RESOLUTION
==========

If you install Windows NT on a FAT partition, start in MS-DOS mode and then
replace the affected files (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys)
with the files from the Windows NT CD, or from the service pack, as applicable.

If you installed Windows NT on an NTFS partition, replace the files in one of the
following two ways:

1. Use the Windows NT 4.0 Emergency Repair Disk (ERD) for this system to repair
  the system files.

  WARNING: Ensure that you have a good backup of your system before using the
  ERD. Any services, applications, service packs, and so on, that you added
  after you created the ERD may be affected by using the ERD.

  - or -

2. Install Windows NT 4.0 into a separate directory. Start your computer with
  the temporary version of Windows NT 4.0. Replace the affected files
  (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys) in the original
  installation with the correct version from the Windows NT 4.0 CD or the
  service pack, if you applied one. After you replace the files and start the
  computer without incident with the original version of Windows NT 4.0, it is
  safe to remove the temporary version of Windows NT 4.0.

MORE INFORMATION
================

When you install Diskeeper for Windows NT 3.51, it replaces the following files:
Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys. The original files are
renamed with an .org file extension. When you use the uninstall option in
Diskeeper, the original files are renamed, replacing the Diskeeper version of
these files. When you uninstall Diskeeper for Windows NT 3.51 after you install
Windows NT 4.0, the Windows 4.0 version of these files are replaced by the
Windows 3.51 version.

To prevent this problem, uninstall Diskeeper before installing Windows NT 4.0.

Executive Software has announced an updated version of Diskeeper for Windows NT
4.0. For additional information, please contact Executive Software.
