Archive: Installed application auto-update

Installed application auto-update
The instalation using NSIS works fine. My installed application is java. Is starting a first jar file, which checks for update and downloads the other jars.

Unfortunatelly it cannot overwrite the existing jars with the downloaded jars. Looks like it requires 'Run as administrator'...etc.
Is any simple way to avoid this ? Maybe make the installed folder writable by anyone ?

Thank you for help,

If installer requires administrative privileges use RequestExecutionLevel admin this way when your installer starts with admin right, all child processes will run as admin.
