Failed to retrieve components whose CLSID is {00024500-0000-0000-c000-000000000046} in the com class factory because of the following error: 80070005. The solution is as follows:

1: Install the Excel software for office on the server.

2: Enter dcomcnfg.exe in "start"-> "run" to start "Component Service"

3: Double-click "component service"> "computer"> "my computer"> "DCOM configuration"

5. Click the "ID" tab and select "Interactive User"

7: the "Security" label remains. Click "Custom" on "Access Permissions", and then click "edit ", in the pop-up "security" dialog box, add a "newuser \ iusr_newuser" user and grant "local access" permission. in this way, we have configured the corresponding Excel DCOM permissions.

8: the "Security" label remains. Click "Custom" on the third "set permission limit", and then click "edit ", in the pop-up "security" dialog box, add the following Permissions

Administrators, System, all rights
Power Users, users fetch

Note: This is configured on win2003. On 2000, it may be because the ASP net user is configured to open the Excel file on the server. Therefore, you should write a file to save the exported data to the server, then pass the method to the client, and delete all the Excel files generated on the server each time you call this function.
