Check for updates and update

Hi,

I'd like to implement a check fpr updates and update the program - would there be a viable way to do so?

Thx

For Lazarus there is LazAutoUpdater (https://wiki.freepascal.org/LazAutoUpdater). I don't know if it can work in a pure FPC program.

It will probably work, but it has no proper roll-back features:
1. stopping the update while running does not always work (from the zip phase onwards)
2. there is no way to recover from a successfull update, but a non-running updated application
3. frankly there is no roll-back at all

Therefor I can not recommend it in the state I last examined it.
I actually get compliments for being rude... (well, Dutch, but that is the same)

Do as Notepad++. It downloads an installer and runs it, then closes the main process, then you can upgrade with a full installer.

The installer is made with Inno Setup.

Thank you for your thoughts!

As I'm writing a GUI-program, that would be okay. I'll have a closer look.

I'll ponder this point, too.

This sounds interesting - I'll give it a try.

In every case I have to switch from ini-file in program directory to either registry usage or ini-file in appdata  :-X

I do not understand why you need that to update your software, I personal never used any pre-made component/code that does do this, I download from internet a small xml file, in that file is the current version written, compare it to installed version, either update or not (depending on my own needs I either create backups for roll-backs first or straight replace files).
