Frequently Asked Questions
Can I fully activate Office 2019 without an internet connection?
While the installation process can be performed completely offline using the image file, you generally need to connect the computer to the internet at least once to sign in and verify the license for activation.
What kind of removable media do I need to transfer the Office 2019 installer?
You can use any removable media, such as a USB flash drive or an external hard drive, provided it has at least 8GB of free space to accommodate the large offline image file.
Why don't I see an 'Offline Installer' option for my Office 2019 Professional Plus?
Office 2019 Professional Plus is a volume-licensed product meant for organizational use. It does not provide a standard retail offline installer. You must use the Office Deployment Tool (ODT) or contact your IT department for the deployment files.
Can I delete the image file from my offline device after installation?
Yes, once the installation process is successfully completed, you can safely delete the image file or remove the USB drive to free up storage space on your device.
