If you are trying to install the same version of 64bit Access Database Engine and 32bit Microsoft Office, you will get an error messages: "You cannot install the 64bit version of Microsoft Access Database Engine because you currently have 32bit products installed..." But you can install the different version of Office and Access Database Engine to solve this issue. For example: Office 2013 32bit + Access Database Engine 2010 64bit Office 2016 32bit + Access Database Engine 2010 64bit Office 2013 64bit + Access Database Engine 2010 32bit Office 2016 64bit + Access Database Engine 2010 32bit If you still got the error, you can use the "/passive" command line parameter to install it: AccessDatabaseEngine[_x64].exe /passive
