I have a addin used by several users. One of the sheet in addin is
used for recording data.
Now I have added some more functions and want to distribute the same
to users.
I can not ask users to just replace addin file coz it will affect the
existing records.
Also only one or two module is updated and rest of the module and
forms are same.
Problem here is that users are not experts and may goofeup.

Is there any way I can do it automatically?
Or any other better way?

Regards,
Madiya.
