Использование библиотек на основе баз данных при установленном на одном компьютере 32- и 64-разрядных версиях ПО Altium

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Database Libraries (DbLibs) are a popular and powerful component management solution. However, when using Microsoft Access as the backend database for your components, there is one important difference between using 32-bit and 64-bit versions of Altium Design Software:

  • 64-bit Altium Design Software (Altium NEXUS) - requires 64-bit Microsoft Access Database Engine to be able to use MS Access with database libraries (DbLibs).
Typically, the appropriate version of Microsoft Office would be installed, of which Access is a constituent part. However, it is likely that many users will have both 32-bit and 64-bit versions of Altium Design Software running on the same computer. The issue is that Microsoft does not officially support, nor endorse, the coexistence of both 32-bit and 64-bit Office applications and drivers on the same computer.

Altium suggests the following three solutions:

  1. Download and install the 64-bit Microsoft Access Database Engine (2010), alongside your existing install of 32-bit Microsoft Office.
  1. Download and install the 64-bit Microsoft Access Database Engine (2010) first, followed by 32-bit version of Microsoft Office (featuring Access).
Note that this solution only works with 32-bit Microsoft Office 2007. It does not work with 32-bit Microsoft Office 2010, 2013, or 2016.
  1. Download and install both the 32-bit and 64-bit Microsoft Access Database Engines (download file includes both), when Microsoft Office (with Access) is not available.
