问题
After getting enlightenment from this post , i've changed the flow.
I asked the user to upload the excel so i can manipulate it later. and then i got error :
Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.
You can see the screenshot here : https://twitter.com/itsCYD/status/570134973128302592/photo/1
i googled for solution and found this : https://waheedrous.wordpress.com/2014/01/26/error-office-interop-assemblies/
the new problem is, Microsoft Excel Application or CLSID {00024500-0000-0000-C000-000000000046} is not found in DCOM.
and then i install the Interop Assemblies and refresh the DCOM. it's still not there.
Need Help.
Thousand Thanks.
