Solution 1Recommended

Temporarily Disable Antivirus and Firewall Software

Active security software can sometimes block Microsoft Office installation files from downloading or writing to the disk, triggering error 30033-44.

Overly strict firewall or antivirus settings can misinterpret legitimate Office installer background processes as threats. Temporarily turning them off is a standard troubleshooting step to allow the installation to complete successfully.

1
Access Windows Security

Click the Start menu, type 'Windows Security', and press Enter to open the security dashboard.

2
Disable Real-Time Protection

Navigate to 'Virus & threat protection', click 'Manage settings' under Virus & threat protection settings, and temporarily toggle off 'Real-time protection'.

3
Turn Off Windows Firewall

Go to 'Firewall & network protection' on the left sidebar, click on your active network (usually labeled 'Active'), and toggle off 'Microsoft Defender Firewall'.

4
Retry the Installation

Run the Office Professional Plus 2013 installer again. Once the installation is fully complete, immediately return to the Windows Security app to re-enable both your antivirus and firewall settings.

Security Reminder: Do not browse the internet or download additional files while your antivirus and firewall are disabled to keep your system secure.

Frequently Asked Questions

What causes error code 30033-44 during Office 2013 installation?

This error is typically caused by third-party antivirus software or a strict firewall blocking the installer from downloading necessary background files. It can also occur if there are residual files from a previous Office installation conflicting with the new one.

Is Office Professional Plus 2013 fully compatible with Windows 11?

While Office 2013 can generally run on Windows 11, it is an older software that has reached its end of support. You may occasionally encounter installation hurdles, which is why running the installer as an administrator or using compatibility mode might be necessary.

What should I do if disabling the firewall doesn't fix error 30033-44?

If disabling your firewall and antivirus doesn't work, download and run the Microsoft Support and Recovery Assistant (SaRA) tool. This official tool can completely wipe any corrupted or partial Office installations from your system, allowing you to start a fresh installation.

Is it safe to temporarily turn off Windows Defender to install Office?

Yes, temporarily disabling real-time protection to install trusted software directly from Microsoft is perfectly safe. Just be certain that you do not browse other websites or download unknown files during this time, and turn the protection back on immediately after.
