When you install Access OLE Export, you find that both the 32-bit and 64-bit versions are installed.
This is because when you access an Access database, you will need to use the 32-bit version of Access OLE Export if you have installed the 32-bit version of Microsoft Office on your machine, or if you have the 32-bit version of the Access Database Engine 2010 Redistributable installed. If you have installed the 64-bit version of Office, or the 64-bit version of the Access Database Engine 2010 Redistributable, you will then need to use the 64-bit version of Access OLE Export.
The Access Database Engine Redistributable itself needs to match the version of Office that’s installed. For example, if you have the 32-bit version of Office installed, and you try to install the 64-bit version of the Engine, you are prevented from doing so.
If you selected the wrong version of Access OLE Export to access your Access database, the following message is displayed.
Simply use the other version then. Alternatively, you can use the Access OLE Export (Access mode) shortcut which will start the appropriate version of Access OLE Export depending on which version of Office is installed on your machine.
