/*++

Routine Description:

   Display a dialog allowing the user to enter a license certificate
   into the system.

Arguments:

   pszServerName (LPCSTR)
      Name of the server for which licenses are to be installed.  Note that
      this may not be the same as the server on which licenses are actually
      installed, as, for example, per seat licenses are always installed on
      the enterprise server.  A NULL value indicates the local server.
   pszProductName (LPCSTR)
      Product for which licenses are to be installed.  A NULL value indicates
      that the user should be allowed to choose.
   pszVendor (LPCSTR)
      Name of the vendor of the product.  This value should be NULL if
      pszProductName is NULL, and should be non-NULL if pszProductName is
      non-NULL.
   dwFlags (DWORD)
      A bitfield containing one or more of the following:
         CCF_ENTER_FLAG_PER_SEAT_ONLY
            Allow the user to enter only per seat licenses.  Not valid in
            combination with CCF_ENTER_FLAG_PER_SERVER_ONLY.
         CCF_ENTER_FLAG_PER_SERVER_ONLY
            Allow the user to enter only per server licenses.  Not valid in
            combination with CCF_ENTER_FLAG_PER_SEAT_ONLY.
   pszSourceToUse (LPCSTR)
      Name of the secure certificate source to use to install the certificate,
      e.g., "Paper".  A NULL value indicates that the user should be allowed
      to choose.

Return Value:

   ERROR_SUCCESS     (A certificate was successfully entered into the system.)
   ERROR_CANCELLED   (The user cancelled without installing a certificate.)
