Fortunately, you should be able to fix this issue by repairing the Office installation. After you do this, you should be able to uninstall the Office tool without issues or upgrade it.

Here’s how to fix Office installation issues:
4. Switch to a wired connection (if applicable)
If you are not currently utilizing a wired Internet connection, connect your device to the Internet and try installing Office again. This procedure is applicable in situations where you are connected to a Wi-Fi network with internet access provided by an ISP that is using Level 3 nodes. In this case, connecting your PC via ethernet cable before restarting the installation or uninstallation of the Office suite should help you fix the issue entirely.
5. Install or Uninstall in a different location
If you are attempting to install Office at work or school, the network may have restrictions that prevent installation. If this is the case, try installing Office again from your home, a friend’s home, or a wifi hotspot. Most commonly, organizations will restrict the installation of software that is not whitelisted, so that’s probably the reason why you are experiencing the 30180-4. Note: If you must install Office at work or school, your IT department may be able to assist you in overcoming any network restrictions. Contact the network administrator and ask him for a way to temporarily lift the descriptions so you can install or uninstall the Office suite.
6. Disable or uninstall proxy or VPN settings (if applicable)
If a proxy or VPN application interferes with the server authentication module of Microsoft Office, the installation or removal of the Office Suite will fail with error 30180-4. If you use your device at both home and work, disable the proxy settings or uninstall the VPN module before opening the setup again. Depending on whether you are utilizing a proxy or a VPN, the necessary procedures may vary. We’ve created two sub-guides that will help you disable both a VPN and proxy connection. Follow the connection that’s applicable to your particular scenario:
Disable VPN Connection
If your VPN connection was established from the VPN connection tab, you can only disable it via the Network & Internet Connections menu. Here are the steps required to disable a native VPN connection:
Disable Proxy Connection
To disable the proxy connection and prevent the interference with the installation or uninstallation of the Office Suite, you must navigate to the Settings menu and disable the active proxy from the Proxy tab. Inside, you will be able to verify if the proxy server is active and disable it if necessary. Here’s how to do this:
7. Disable Windows Defender or firewall
If you are trying to install or uninstall an older Office suite, certain AV or firewall suites might see flag the operation as potentially dangerous. Before retrying the operation, take the time to disable any third-party anti-virus software or firewall. Test this hypothesis by accessing your AV or firewall settings and disabling it temporarily before retrying the Office operation. Note: Keep in mind that while some AV suites will allow you to disable the real-time protection via the taskbar icon, most won’t. In most cases, you’ll need to access the settings menu and disable it from them. The same goes for a standalone 3rd party firewall. You should also consider removing the third-party suite completely, particularly if you’re using an antivirus package that includes a firewall. If you choose this path, utilize this removal procedure to ensure that you leave no leftover files behind before retrying the Office installation.
