There are various ways to fix the problem:

1. Use tip 181 to copy the file from the CD-ROM. You may have to reapply your latest Service Pack.

3. Check the Software Hive for corruption by booting to an alternate install of Windows NT and loading the original Software Hive using tip 182. When locating the Software Hive, it is the Software file with the Windows Icon, not the Notepad icon. If you receive a Registry Editor could not load ..... message, the software Hive is corrupt. You must restore the registry or run a repair / repair registry files.
