While Running website on server showing Excel error?

Question

At the time of filling data into excel it is showing following error message

 

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

 

It  is working  well in local system  but after hosting it is showing error, please tell me the solution to this.
