Using Database Libraries with 32-bit and 64-bit Altium

To support both AD17 and AD18 you need to use a 32bit version of MS Office and a 64bit Access Database Engine.  

Note the Access Database Engine is NOT the same thing as Access or Access Runtime.

The 64-bit Access Database Engine installs 64-bit ODBC drivers which allow 64-bit applications like AD18 to connect to data sources.

You can find ODBC drivers installed on your PC in Win 10 by entering ODBC in the search window.

In the link below Altium suggested thee possible solutions to connect both (AD17) 32bit and (AD18) 64bit versions of Altium to Microsoft Excel and Access data sources.

Solution 1 (Install 64bit Office) applies to only AD18. You can NOT bounce back and forth between AD17 and AD18 if you install a 64bit version of MS Office.  

Solution 1 does not apply to AD17 and earlier 32bit versions of Altium.

To support both AD17 and AD18 you need to use a 32bit version of MS Office and a 64bit Access Database Engine.

Solutions for Office 2007 and AD17 / AD18 DBLib Access databases.

Solution 1

You may need to uninstall all existing Access Database Engines, then reinstall the 32-Bit Microsoft Access Database Engine.

And then install 64-bit Microsoft Access Database Engine (2010) from the Command Prompt using the / passive switch.

Solution 2

I used a variation of the Altium Solution #3 for Office 2007.

I had trouble completing the uninstall for Office 2007.  I used a Microsoft easy fix tool to completely uninstall Office 2007 and clean up the machine's registry.

The key to success is to get AD17 working first then install the 64-bit Access Database Engine as recommended for AD18.

That's it !
