Windows 11 – Legacy application fails with “Class not registered” (DAO 3.5 CLSID)

by |Published

I’m trying to run an old application called Archive CS5 (version 2.0.0.10) on Windows 11 64-bit.

When launching the application, I receive the following error:

Class not registered. Looking for object with CLSID: {00000010-0000-0010-8000-00AA006D2EA4}

Based on my research, this CLSID appears to be associated with Microsoft DAO 3.5.

Here is what I’ve discovered so far:

  • DAO350.dll (version 3.50.3602.0) is present on my system.
  • dao360.dll is also present.
  • DAO.DBEngine.36 is registered.
  • DAO.DBEngine.35 is not registered.
  • Attempting to register DAO350.dll using the 32-bit RegSvr32 results in error 0x80004005.
  • The DAO 3.6 TypeLib registry entries are present.
  • Both DLL files are located in the Microsoft SharedDAO directory.

I would appreciate advice on the correct way to install or register Microsoft DAO 3.51 on Windows 11 64-bit.

Is there an official or reliable DAO 3.51 installation package that can restore the required COM registrations?

I’ve attached a diagnostic report containing Windows, DLL version and registry information.

Here is my CMD logs:
