在同一台计算机上使用带有32位和64位Altium设计软件的数据库元件库

When using Microsoft Access as the backend database for your Database Libraries (DbLibs), there is one important difference between using 32-bit and 64-bit versions of Altium Designer:

  • 64-bit Altium Designer (Altium Designer 18.0 and later) – requires 64-bit Microsoft Access Database Engine to be able to use MS Access with database libraries (DbLibs).
  • 32-bit Altium Designer (Altium Designer 17.1 and earlier) – requires 32-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, if there is a need to have both 32-bit and 64-bit versions of Altium Designer 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 two solutions:

  1. When Microsoft Office (with Access) is not available, download and install the 64-bit Microsoft Access Database Engine (2016).
  2. When a 32-bit version of Microsoft Office (featuring Access) is available, download and install the 64-bit Microsoft Access Database Engine (2016) first, followed by Microsoft Office.

    Note that this solution only works with 32-bit Microsoft Office 2007. It does not work with a later version of 32-bit Microsoft Office.
