Fixing Internal Error 28173 in VMware: Causes, Impacts, and Solutions

If we’ve encountered Internal Error 28173 during the installation of VMware vCenter or vSphere Client, we’re not alone. This error typically arises when the necessary Microsoft .NET Framework 3.5 isn’t enabled or installed on the Windows system. Understanding the error, its implications, and how to resolve it is key to keeping the VMware environment running smoothly. In this article, we break down the meaning of the error, its potential impacts, common causes, and effective solutions.

What is Internal Error 28173?

Internal Error 28173 is an installation issue that occurs when VMware’s setup process is unable to enable Microsoft .NET Framework 3.5, which is crucial for the proper functioning of VMware vCenter Server and vSphere Client. These tools are essential for managing the virtual environment, so encountering this error during installation can be a significant roadblock.

The error message typically appears as:

This error commonly occurs during the installation process of VMware products, particularly when installing on a Windows-based system without the required version of .NET Framework 3.5 enabled.

Impacts of Internal Error 28173

The Internal Error 28173 can have several notable effects on the virtual environment and IT operations:

1. Installation Failure: The most immediate consequence is the failure to install VMware’s vCenter or vSphere Client, halting the ability to manage virtual machines effectively.

2. Operational Disruption: Without these essential management tools, administrators may find it difficult to deploy, monitor, and optimize virtual machines, leading to significant operational delays.

3. Increased Downtime: Dealing with this error requires time and effort, resulting in unnecessary downtime and delays in IT projects.

4. Resource Management Challenges: Without functional management tools, administrators may struggle with efficient resource allocation, leading to suboptimal use of hardware.

5. Security Risks: Prolonged delays in installation can leave systems vulnerable to unpatched security threats, particularly in environments where updates and patches are necessary for system integrity.

Common Causes and How to Fix Internal Error 28173

Understanding the root causes of this error will help us resolve it efficiently. Here are the most common causes and their corresponding fixes:

1. Missing .NET Framework 3.5

Cause: The most common cause is that .NET Framework 3.5 is either missing or disabled on the system.

Fix:

i. Open Control Panel and navigate to Programs > Turn Windows Features On or Off.

ii. In the list, check the box next to .NET Framework 3.5 Features.

iii. Click Next and follow the prompts to install or enable .NET Framework 3.5.

iv. After installation, restart the system and attempt the vCenter or vSphere Client installation again.

2. Windows Server Configuration Issues

Cause: On Windows Server systems, specific configurations might prevent enabling .NET Framework 3.5.

Fix:

i. Ensure that the server has internet access or installation media.

ii. If we receive a message indicating that Windows cannot find required files, insert the Windows setup media or connect to the internet to allow Windows to download the necessary files.

3. Corrupted Installation Files

Cause: Corrupted or incomplete installation files can cause this error during VMware setup.

Fix:

i. Re-download the VMware installer from a reliable source to ensure the file is complete and not corrupted.

ii. Retry the installation with the new installer.

4. Insufficient User Permissions

Cause: The account performing the installation may lack the required permissions to modify system settings.

Fix:

Right-click on the installer executable and select Run as administrator to ensure elevated permissions during installation.

5. Conflicting Software

Cause: Antivirus or other security software might be interfering with the installation process.

Fix:

i. Temporarily disable any antivirus or security software before starting the VMware installation.

ii. Once the installation is complete, we can re-enable the security software.

How to Avoid Internal Error 28173?

To prevent encountering Internal Error 28173 during future installations, follow these best practices:

i. Ensure Prerequisites Are Met: Always confirm that .NET Framework 3.5 is installed and enabled before starting VMware installations.

ii. Regularly Update Windows: Keep the Windows operating system up to date to avoid configuration issues and ensure that all features are correctly enabled.

iii. Clean Installation Environment: Where possible, perform installations in a clean environment with minimal software running to reduce the chances of conflicts.

iv. Backup System Settings: Before performing major installations or updates, back up the system settings to make it easier to recover if something goes wrong.
