Microsoft Office Error Code 30174-4 - 1

Microsoft Office Error Code 30174-4

Most notoriously, the antivirus program on your PC or any firewall in your network can cause this. As such, you will either need to tweak them by adding an exception or temporarily disable the said programs to allow the installation to complete. In this article, we will take you through the various methods needed to resolve the error code in question, so follow along.

1. Use the Offline Installer

One of the first ways you can get around the error code in question is to use the offline installer. By default, when you download the installer for Office, it only downloads the installer on your computer, and not all of the files required to install Office.

This is because the installer is used to download the latest Office files via your network connection to be installed on your computer. While this saves you from the trouble of downloading a huge setup file, the installation essentially takes longer because the files are downloaded on the go.

In contrast, you can use the offline installer as well to install Office on your PC. This allows you to install Office without an active internet connection once you have downloaded the installer since all of the files come with the initial download.

To use the offline installer, simply sign in to your account on the Office website and download the offline installer instead of the typical setup file. The offline installer is usually located under the Other options section on the Installs page of the Office website. Once you download the installer, run the setup file respective to your Windows architecture (x86 or x64) to proceed with the installation.

2. Use Another Network Connection

Another way you can overcome the error code while installing Office on your PC is to use a different network connection. This can act as a quick fix when your current network connection is unable to resolve the request to the Microsoft Office servers.

There are numerous reasons that can cause this behavior, and if you are looking for an easy fix, using a different network connection would be the right choice for you. You can achieve this by using your mobile’s hotspot for mobile data and connecting to the network on your computer. Use the new connection to run the Office setup file and see if the problem persists.

3. Disable Antivirus (Temporarily)

A security program running in the background on your PC alongside the Office setup file can be another cause for the error code in question. This happens when the antivirus program prevents the Office setup from establishing a connection to its respective servers.

Such a scenario is quite common with the network security features in modern antivirus programs. In such an instance, you will need to disable the antivirus app on your PC temporarily till the Office setup is completed.

If you do not want to disable the antivirus program, you have the option of adding the setup file as an exception to your antivirus settings. This will prevent the security app from interfering with the setup file, and it should be able to proceed without any issues.

4. Turn off VPN (if applicable)

If you are using a VPN connection on your computer, that can also cause the mentioned error code while installing Office. VPN programs often use tunneling that essentially routes your network traffic through several secure servers before reaching the destination.

This can result in the packet sometimes getting lost or the end server dropping the connection which results in the 30174-4 error code. To resolve this, you will need to turn off any VPN connection you are using. If you have added a VPN client to Windows, follow the instructions below to disconnect it:

  1. First, press the Windows key + I to bring up the Settings app.
  2. Go to Network and Internet > VPN in the Settings app. Navigating to VPN Settings
  3. After that, click the Disconnect option next to your VPN.
  4. If you want to remove the VPN connection, click on the down arrow and select Remove . Removing VPN Connection

5. Disable Firewall

A firewall in your network can also prevent the setup file from connecting to Office servers which results in the issue in question. This is because firewalls are used to manage and monitor the incoming and outgoing requests in your network or device, depending on their level of implementation.

As such, you will need to disable the firewall for a little while till the installation is complete. We are going to show you how to disable the Windows Defender Firewall below. However, if you have any other firewalls on the network level, you will have to add an exception or disable them temporarily.

Follow the instructions below to disable the Windows Firewall:

  1. First, use the Start Menu to open the Control Panel . Opening Control Panel
  2. Then, go to System and Security > Windows Defender Firewall in the Control Panel. Navigating to System and Security
  3. After that, click on the Turn Windows Defender Firewall on or off option on the left. Navigating to Turn off the Firewall Screen
  4. Select the Turn off Windows Defender Firewall option under both Public and Private settings. Disabling Windows Firewall
  5. Finally, click OK.
  6. See if the problem goes away.

6. Remove Older Office Installations

Finally, if you have an older version of Microsoft Office installed on your system while you try to run the setup file for a newer version, it can cause the problem to occur. To remedy this, you will need to uninstall and remove files of the older Office installation on your computer.

Uninstalling Office from your PC is quite easy. In case the problem persists after you uninstall any older version of Microsoft Office, you will need to perform a thorough uninstall depending on your Office version. You can read the linked official Microsoft documentation for this.

Follow the instructions below to uninstall Microsoft Office:

  1. Open the Control Panel by searching for it in the Start Menu. Opening Control Panel
  2. Then, select the Uninstall a program option. Navigating to Uninstall a Program
  3. From the list of apps, locate Microsoft Office and double-click on it. Uninstalling Microsoft Office
  4. Go through the on-screen prompts to complete the uninstallation.
  5. After that, run the setup file to see if the error code still occurs.

You should be able to get past the 30174-4 error code with the methods above. Your internet connection is the primary cause of the issue in question. As such, ensuring the Office connection is not being blocked in your network should help you prevent the issue in future.

How to Fix “Printer is in an error state” Issue?

The error “ WinRAR Error: Next Volume Is Required ” usually appears when you’re extracting a multi-part RAR archive and WinRAR can’t find (or can’t correctly identify) the next file in the sequence . This often happens when a volume is missing , stored in a different folder , or renamed in a way that breaks the archive’s expected order .

Fix: “Error Code 30174 - 3

In this guide, we’ll go over the most reliable fixes confirmed by affected users, along with what each method is doing behind the scenes so you can choose the right one for your situation.

Important: To extract multi-volume archives, you should always start extraction from the first file in the set. This is usually file.part1.rar , or (in older sets) the main .rar file that comes before .r01 , .r02 , and so on.

1. Download and Place the Missing RAR File

WinRAR needs all parts of a multi-volume archive to complete extraction. This error usually appears when one of the volumes in a set like .part2.rar , .r01 , .r02 , .001 , and similar naming formats is missing . Downloading the missing volume and placing it in the same folder as the other parts allows WinRAR to continue extracting normally .

  1. Look at the error message or review the list of archive parts in the folder.
  2. Identify which volume is missing (for example, part2.rar , .r02 , .001 , etc.).
  3. Go back to the website or source where you downloaded the archive.
  4. Locate and download the exact missing file using the same naming format as the others.
  5. Make sure the new file name matches the pattern of the rest. Example: If you have file.part1.rar and file.part3.rar , the missing one must be file.part2.rar .
  6. Move the downloaded missing volume into the same folder as the other archive parts.
  7. Confirm that all parts are in a single folder before extracting.
  8. Right-click the first file in the series (usually part1 or the main .rar file) and select Extract Here or Extract to Folder .
  9. WinRAR should now detect all volumes and continue extraction normally .

2. Manually Browse & Select the Next Volume

Use this method only if the next volume already exists , but WinRAR is failing to detect it automatically. This can happen due to incorrect naming , the file being in a different location , or a temporary file access issue. Manually browsing helps WinRAR locate the correct volume and resume extraction without interruption .

  1. Right-click the first file in the series (usually .rar or part1.rar ) and select Extract Here or Extract to Folder .
  2. When WinRAR cannot find the next volume, it will show the “ Next Volume Is Required ” message.
  3. A small window will appear, allowing you to manually select the next volume .
  4. Use the file explorer window to locate the folder where the other archive parts are saved.
  5. Select the next part based on the naming order (example: select file.part2.rar after file.part1.rar ).
  6. Make sure the selected file matches the naming format of the archive (no extra characters like (1) and no mismatched numbering).
  7. WinRAR will resume extraction using the selected volume .
  8. If additional volumes are missing or stored separately, WinRAR may prompt you again. Repeat the same process until extraction completes.

3. Rename the RAR files in Order

WinRAR relies on a proper naming sequence (such as file.part1.rar , file.part2.rar , file.part3.rar ) to extract multi-volume archives. If a file is named incorrectly, contains extra characters, or is out of order, WinRAR may fail to locate the next volume and show this error. Renaming the files correctly helps WinRAR follow the sequence and extract the archive without interruptions .

Note: Renaming only changes the file name , not the file contents. The goal is to restore the correct sequence so WinRAR can detect the next volume.

  1. Go to the folder where all the RAR files are saved.
  2. Make sure all parts of the archive are present and stored in the same folder .
  3. Check how the parts are currently named . Common patterns include:
file.part1.rar, file.part2.rar, file.part3.rar
file.rar, file.r01, file.r02, file.r03
  1. Look for files that don’t match the expected numbering pattern (for example, file.part01.rar , file.part1(1).rar , or unrelated names).
  2. Rename each file so it follows the same order without extra characters or mismatched numbering. Example:
Incorrect: file.part1.rar, file.part3.rar, file.part2(1).rar
Correct: file.part1.rar, file.part2.rar, file.part3.rar
  1. Make sure the text before the number is exactly the same for all files.
  2. Only the last part number should change.
  3. Right-click the first file in the series (usually part1.rar or the main .rar file) and select Extract Here .
  4. WinRAR should now recognize the sequence and continue extraction normally .

If you still get the same prompt: the archive set is likely incomplete (a part was never downloaded or was removed), or one of the volumes is corrupt and must be re-downloaded from the original source.
