Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Thanks for sharing the screenshot. The “Administrative Privileges Required” error while installing Office from portal.office.com is a local Windows permission issue, not a Microsoft 365 license or account problem.
The message “Administrative Privileges Required” (Error Code 0‑2005 (1223)) appears when:
- The Windows account you’re currently signed into does not have local administrator rights, or
- You did not approve the User Account Control (UAC) prompt during installation
Office installation requires permission to make system‑level changes, which standard (non‑admin) Windows accounts cannot do by themselves.
You can fix it by trying the following steps:
- Run the installer explicitly as Administrator
After downloading OfficeSetup.exe:
- Open your Downloads folder
- Right‑click OfficeSetup.exe
- Select Run as administrator
- When prompted by Windows, select Yes
- Make sure your Windows account is a local administrator
If the error continues, confirm your account has admin rights:
- Go to Control Panel > User Accounts > Change your account type
- Your account must be listed as Administrator
Please follow this guide to check if you have admin rights: Check if you have local admin rights to install Office - Microsoft Support
- Ensure User Account Control (UAC) is enabled
Office setup will fail if UAC is turned off:
- Control Panel > Security and Maintenance
- Expand Security
- Confirm User Account Control is On
Restart the PC after enabling it, then retry the install.
