Updating C++ Programs After Release

[Smarty]

I'm thinking ahead.

So, I have this program, it has saved information, and I want to know how to update the program without deleting the saved information.

I have Inno Setup, can I use that to update it without deleting my saved information?

Most companies set up to update without removing the data. If it is one of your own home made applications then it would depend on a few factors.

can you use Inno setup to update?
