3.10.4.2 IsInstalledRemote (Opnum 12)

  • Article

The IsInstalledRemote method determines if a certificate is associated with the specified InstanceName.

 [id(6)] HRESULT IsInstalledRemote(
   [out, retval] VARIANT_BOOL* retval
 );

retval: A pointer to a VARIANT_BOOL.

Return Values: A signed 32-bit value that indicates return status. If the method returns a negative value, it failed. If the 12-bit facility code (bits 16–27) is set to 0x007, the value contains a Win32 error code in the lower 16 bits. Zero or positive values indicate success, with the lower 16 bits in positive nonzero values containing warnings or flags defined in the method implementation. For more information about Win32 error codes and HRESULT values, see [MS-ERREF].
