uploading .xlsx formate to database error raises?

hi

 Iam uploading .xlsx file to database using connection: "Provider=Microsoft.Jet.OLEDB.12.0; Data Source=" + SourceUpload.Fullpath + "; Extended Properties='Excel 8.0;IMEX=1;HDR=(9);'";

Raises an error like this The 'Microsoft.Jet.OLEDB.12.0' provider is not registered on the local machine.

Then i was downloaded 2007 office system driver:data connectivity components  and installed

After that also same error is showing The 'Microsoft.Jet.OLEDB.12.0' provider is not registered on the local machine.

I was tried this link also http://www.codeproject.com/Tips/417397/OLEDB-Provider-is-Not-Registered-on-the-Local-Mach

modifying configuration manager adding x86 in active solution platform but there is no use same problem The 'Microsoft.Jet.OLEDB.12.0' provider is not registered on the local machine.


i hope correct solution for this problem as earlier as possible.....
