  • You may (if not already done) install the microsoft office database engine. If you have installed the engine then look at the compile tab for the project, what are your setting for "Target CPU" and "Prefer 32-bit" ? On my computer, 64 bit I have the 32 bit engine with these settings for working with the OleDb data provider (which it appears you are attempting to use).

  • Hi jamilaid,

    The ACE provider is not installed on Windows operating systems by default. You have to install it. The ACE provider is available in two forms: Microsoft Office Access database engine 2007 and the Microsoft Access Database Engine 2010 Redistributable. The 2007 version is only available as a 32-bit component whereas the 2010 version offers both 32 and 64-bit options. You need to be careful which option you choose, because a wrong choice here is the most frequent cause for the error message.

    You can install the 2010 64-bit version. If you have the 2007 32-bit version installed, you can simply install the 2010 64-bit version alongside it. If you have the 32-bit version of 2010 installed, you need to uninstall it and download and install the 64-bit 2010 version instead. You cannot have both the 32- and 64-bit versions of the 2010 provider installed at the same time.

    Best Regards,

    Cherry
