The MS Enhanced Provider (Rsaenh.dll) is a Cryptographic Service Provider for the Crypto API that implements strong Cryptography (DES, 3DES, 128-bit RC2 and RC4, and large RSA key exchange keys). Its export is restricted to North America and, in this case, it is shipped in the Domestic (North America only) version of Windows NT 4.0 Service Pack 3.

To fix this problem:

1. Make sure that you have downloaded the appropriate file for your platform (Rsax86.exe for the X86 platform or Rsaalpha.exe for the Alpha platform).
2. Run the .EXE to extract the Rsaenh.reg file.
3. Make sure that you are logged on as an administrator.
4. Go to a DOS window. At the command line type:

   regedit rsaenh.reg

   The command argument to regedit.exe must be the path of the rsaenh.reg file.
