Frequently Asked Questions
Why do I keep getting error 0-2048 during Microsoft 365 installation?
This error usually indicates that your device cannot establish a stable connection to Microsoft's download servers. It is often blocked by strict firewall settings, proxies, or an active VPN connection.
Will temporarily disabling my antivirus harm my computer?
As long as you only download the Microsoft 365 installer from the official website and immediately re-enable your antivirus after the installation is complete, your computer remains safe.
