The Microsoft.jet.OLEDB.4.0 pr开发者_运维问答ovider is not registered on the local machine

what can be the problem ?

Your software is running in 64 bit mode, and the ODBC driver is 32 bit only.

You should change the manifest to run with 32-bit version of .Net. You can do this from the Visual Studio Configuration options.
