Hi all,

i am facing problem below:
Class does not support Automation or does not support expected interface

original is using Microsoft ActiveX Data Object Library 2.8

Only some PCs facing this problems.

Then i changed it to 2.7 then saved it and change back to 2.8 and saved.
Then users can open it already.

May i know why it happen???
i need to change from 2.8 to 2.7 then change it back to 2.8, then the problem is solved.
Is it a bug?
