The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine error in windows server

问题

I am using a excel reader to read contents from the excel,

  string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;
                 Data Source=" + filePath + ";Extended Properties=Excel 12.0;";
  System.Data.OleDb.OleDbConnection ExcelConnection 
                 = new System.Data.OleDb.OleDbConnection(connectionString);

I'm working in VS2010 on a windows 7 ultimate x64 installation. it works fine in my local machine when I run with VS. When I upload the website in server I get the following error. What should I do here, I have access to the server. Thanks

The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. Error

Yes. Be aware that there will be different versions dependent on whether you are running on 32 or 64 bit architecture.
