Office 365 Offline Installer Exclusive < 2026 >

Once you have your ISO or EXE file (the exclusive package), installation is straightforward:

Q: Can I use the offline installer on Windows 7? A: Officially, Microsoft 365 Apps no longer support Windows 7 (ended January 2023). The installer will likely fail or install an unsupported version.

Q: Does the offline installer include updates? A: It includes all updates up to the date you downloaded the file. You will need to run Windows Update or manually refresh your offline source monthly to get security patches.

Q: I have a perpetual license (Office 2021). Does this apply to me? A: No. Office 2021 (LTSC) is a different product. It has its own offline ISO. The "Office 365" installer requires a recurring subscription.

Q: How big is the file? A: Approximately 3.2GB for 32-bit, 3.8GB for 64-bit, or up to 5GB if you include both architectures and all languages.

This is where the magic happens. The configuration.xml file is a set of instructions that tells the setup file what to do. To create an offline installer, you must configure this file to download the source files rather than install them immediately.
