I am hosting a web application which uses OLEDB 12 to read an Excel file, but getting the error "'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine". Wonder if I should use lower version of OLEDB or Azure does not support OLEDB services at all. Before rewriting the program, just wanted to see if anyone knows a better alternative. I am using Visual Studio 2010 for my development. Thanks in Advance.
