Please refer to Retrieving the COM class factory for component failed

I just pasted the content of the fix here.

In DCOMCNFG, right click on the My Computer and select properties.

Choose the COM Securities tab.

In Access Permissions, click Edit Defaults and add Network Service to it and give it Allow local access permission. Do the same for < Machine_name >\Users.

In Launch and Activation Permissions, click Edit Defaults and add Network Service to it and give it Local launch and Local Activation permission. Do the same for < Machine_name >\Users.
