In the landscape of productivity suites, few releases have been as pivotal as Microsoft Office 2013. While many users have moved on to Microsoft 365, a significant number of businesses, power users, and legacy system maintainers still rely on Office 2013 64 bits. Why?

If you love the feel of Office 2013 but need security, consider: Only install Office 2013 64-bit if:
Microsoft officially ended mainstream support for Office 2013 on April 10, 2018, and extended support ended on April 11, 2023. Consequently, you cannot buy it from the Microsoft Store anymore. However, if you have a legitimate product key, you can still download it.
Once you have the installer, follow these steps to ensure a smooth setup:
Step 1: Uninstall previous Office versions You cannot run Office 2013 64-bit alongside Office 2007 or 2010 (32-bit). They conflict. Use the official "Microsoft SARA" (Support and Recovery Assistant) to cleanly remove old versions.
Step 2: Run as Administrator
Right-click the Setup.x64.exe file and select Run as Administrator. This prevents permission errors during DLL registration. Otherwise, upgrade to a supported Office version
Step 3: Opt for Customization During the install screen, click "Customize" instead of "Upgrade."
Step 4: The Activation Launch Word 2013. The startup wizard will ask for your product key. Enter it precisely. If you are on a volume license (VL), you need a separate KMS host or MAK key.
Pro Tip: If your key is legitimate but fails, use the phone activation method: Run SLUI 04 (Software Licensing User Interface) from the Run dialog (Win+R).
