The "Microsoft Excel application properties" dialog box is displayed.

5. click the "Security" tab, click "Custom" on "Start and activate Permissions", and then click the corresponding "edit" button, in the pop-up "security" dialog box, add a "Network Service" user (note that you must select the computer name) and grant it the "local start" and "Local activation" permissions.
6. still "security" label, click "Custom" on "Access Permissions", and then click "edit ", in the pop-up "security" dialog box, add a "Network Service" user and grant "local access" permission.

If 5, 6, and 7 are useless, add an "everyone" user.Method 2: Add the following nodes to the <system. Web> node in the web. config file. That's fine. But this is not good. <Identity impersonate = "true" username = "machine administrator login name" Password = "password"/>
