VB6 DAO - importance of registering DAO350.DLL

Last Modified: 2015-12-31
Hi Experts,

I have a number of VB6 applications that use DAO 3.5.

There are 100s of users happily using the applications on Windows XP, 7 and 8.x

But I have struck a problem when I run my setup programs (created with Setup Factory) on my Windows 10 Pro system.

I'm getting this error when running the setup program:
Error      Register COM file: C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL - System Error # 0 (3)
Notice      Register COM failure reason: Error 0x8002801c: Error accessing the OLE registry.

The installed application runs fine - I don't get any errors when using database features.

What I want to know is:  

does it matter to end users if DAO350.DLL is not registered?
can I assume that DAO350.DLL only needs to be registered for developers?
