When I call the COM component in asp.net to publish IIS, I often see the error 80070005 solution.

Many people reference the COM component in the. net development Web site. The debugging is normal, but the following error is prompted as soon as it is published to IIS:

Failed to retrieve components whose CLSID is {} in the COM class factory because of the following error: 80070005

The following solutions are available on the Internet:

Failed to retrieve components whose CLSID is {000209FF-0000-0000-C000-000000000046} in the COM class factory because of the following error: 80070005
