Office Update KB5002160

Microsoft Office 2016 update KB5002160 – released on March 1, 2022,  fixes an issue where a custom application can crash if you use more than one protocol to connect to Microsoft Access or other Office data (for example, Object Linking and Embedding, Database (OLEDB), Open Database Connectivity (ODBC), or Data Access Objects (DAO)). I had reported in the blog post Microsoft Office Updates (March 1, 2022) about the patch, which is only available for the MSI installation versions of Microsoft Office.

After install update KB5002160 is problem with initialize DB engine 2016. My program is freezing.

  1. _DBEnginePtr dbEngine;
  2. DAO_CHECK_ERROR(dbEngine.CreateInstance(__uuidof(DBEngine)), AFX_DAO_ERROR_ENGINE_INITIALIZATION);

In this thread other affected people report, where the access to the Access database from applications hangs. Reinstalling the "Microsoft Access 2016 database engine" only works temporarily, as Windows notices the missing update and reinstalls it if necessary.

One user states as a workaround to install an older version of the Database Engine from the following links:
