hi, i have created a simple database that is linked to msaccess it is working fine and i have also created an installer and have installed it on my pc but now i need to update it without reinstalling because i will lose that information due to the fact that the msaccess file file is encrypted and only the app can decrypt it.
can anyone help me with this issue PLEASE!

What I have tried:

I tried looking online but i haven't find the right thing is always update with links and check for updates but i don't have a website is as simple as creating the patch(i think) and install it.
I do not know if this is relevant but the patch will have to change previously code and also the design.

I also had worked on vb.net + MS Access database for small projects, so do like to help you,
Basically we have project files which includes Database as .mdb and our softwar .exe file.
If we are updating software it means we are doing one of following of below,
1.updating only design and logic.
2.updating database only
3.updating both.

In all scenarios, we can replace .exe file of user with our updated one. And to update database we can write code for it in our application. I personally have written module for updating database. whenever software runs, this module check for database and update it with latest one.
