SYMPTOMS

If you install Microsoft Windows NT Service Pack 3 when Microsoft Enhanced Cryptographic Service Provider (CSP) and Microsoft CyrptoAPI versions 1.0 and 2.0 are installed on your computer, entries for the digital signature may be damaged or missing from the registry. If the CSP is not properly registered, it does not load and no error message is displayed.

The Advapi32.dll file, included with Windows NT Service Pack 3, may generate either of the following error values:

  • 0x8009001A (NTE_KEYSET_ENTRY_BAD)
  • 0x80090006 (NTE_BAD_SIGNATURE)

RESOLUTION

A fix to this problem is available that makes the necessary changes to the registry. To obtain the fix, download the appropriate self-extracting executable file:
