Hello Ahnog,
you can see this error because a program is trying to access a file which cannot be found.
The software is looking for the file updater2.xml in various locations.
Maybe the folder path is not correct anymore and so the file cannot be found.
It seems as the Program "DriverSetupUtility" does have the Problem - This software is a tool for setting up the hardware drivers and keep them up to date. (Acer / Packard Bell "Care Center").
Maybe you can try to reinstall or repair the software and this window should not show again. If you're an experienced user you also can uninstall the software - but in this case you should to check for updates yourselve.
best regards,
Roman
