VirtualBox Product Key Issues? A Quick & Easy Fix Guide

Updated: • 0 • 9 min read

When you’re attempting to install Windows on a VirtualBox Virtual Machine (VM), you might encounter an error message stating: “VirtualBox cannot read the product key.” This frustrating issue can halt the installation process right at the “Setup is starting” stage. This guide will walk you through several effective solutions to resolve this problem and get your Windows installation back on track.

Understanding the “VirtualBox Cannot Read the Product Key” Error

This error typically arises when VirtualBox is unable to access or interpret the product key information required for Windows installation. This can stem from a variety of underlying causes, ranging from corrupted configuration files to conflicts with other software on your system. Understanding the potential reasons behind this error is the first step towards effectively troubleshooting and resolving it.

Solutions to Fix “VirtualBox Cannot Read the Product Key”

If you’re facing the “VirtualBox cannot read the product key” error, try the following solutions one by one until the issue is resolved.

1. Delete the Unattended Configuration File

Corrupted or misconfigured unattended configuration files can often be the culprit behind this error. These files store settings related to your virtual machine, and deleting them can sometimes resolve conflicts and allow VirtualBox to properly read the product key. Don’t worry, this process is safe and will not delete your personal files within the VM. It only removes the VM’s configuration settings.

Steps to Delete Unattended Configuration Files:

  1. Power Off the Virtual Machine: Begin by completely shutting down the virtual machine. Right-click on the virtual machine in the VirtualBox Manager and select “Stop.” Ensure the VM is powered off and not just in a saved state.

  2. Access VM Settings: Right-click on the same virtual machine again and select “Settings” from the context menu. This will open the settings window for your virtual machine.

  3. Switch to Expert Mode: In the Settings window, look for a “Mode” dropdown, usually located at the bottom left corner. Change the mode from “Guided” to “Expert.” Expert mode provides access to advanced settings which are necessary for this step.

  4. Navigate to Advanced Tab and Copy Snapshot Folder Location: In the Expert settings view, go to the “Advanced” tab. Locate the “Snapshot Folder” field. This field contains the path to the directory where your VM’s configuration files are stored. Carefully copy this entire path.

  5. Open File Explorer and Paste the Location: Open File Explorer (or Finder on macOS). In the address bar at the top, paste the snapshot folder path you copied in the previous step and press Enter. This will take you directly to the directory containing your VM’s configuration files.

  6. Delete Unattended Configuration Files: Inside the snapshot folder, look for files that are named like “unattended.xml” or similar unattended configuration files. Delete all files that appear to be related to unattended configurations. Be cautious and only delete files related to VM configuration, and not other files if you are unsure.

  7. Disable Floppy Drive in Boot Order: Navigate to “System” and then the “Motherboard” tab within the VM’s Settings window. In the “Boot Order” section, find “Floppy” in the list. If “Floppy” is checked, uncheck it. Having a floppy drive enabled in the boot order can sometimes interfere with the installation process.

  8. Click “OK” to Save Changes: After completing all the steps, click the “OK” button at the bottom of the Settings window to save the changes you’ve made to your virtual machine’s configuration.

Access VM Settings

Once these steps are completed, restart your virtual machine and attempt to proceed with the Windows installation. Check if the error message is gone and you can move past the setup screen. If the issue persists, repeat the steps to delete the unattended files once more and then proceed to the next solution.

2. Modify Virtual Machine Configuration Settings

Sometimes, the default configuration settings of your virtual machine might not be optimal for Windows installation, leading to the product key error. Adjusting certain VM settings can often resolve compatibility issues and ensure a smoother installation process.

Steps to Adjust VM Configuration:

  1. Open VM Settings: As before, right-click on your virtual machine in VirtualBox and select “Settings.”

  2. Adjust Processor Settings: Go to “System” then “Processor.”

    • CPU Count: Ensure that the “Processors” setting is set to at least 2 CPUs. Windows generally requires a minimum of two processors for optimal performance in a virtualized environment.
    • Execution Cap: Verify that the “Execution Cap” is set to 100%. This ensures the VM has full access to the allocated processor resources.
    • Enable PAE/NX: Make sure the “Enable PAE/NX” checkbox is checked. PAE/NX enhances security and performance, and is generally recommended for modern operating systems.

  3. Adjust Display Settings: Navigate to “Display” then “Screen.”

    • Enable 3D Acceleration: Check if “Enable 3D Acceleration” is enabled. While not always strictly necessary for basic installation, enabling 3D acceleration can improve graphics performance within the VM, especially if you plan to use graphical applications later.
    • Increase Video Memory: Increase the “Video Memory” to 256 MB. Adequate video memory is crucial for smooth display performance within the virtual machine.

  4. Modify Storage Settings: Go to “Storage.”

    • Select Unattended Storage Device: In the “Storage Devices” list, look for an entry that might be named “Unattended” or similar (it might be under a Controller like “IDE Controller”). Select this entry.
    • Remove Unattended Storage Device: Click the “Remove” button (usually a minus sign “-“) to remove this unattended storage device from the VM configuration.
    • Tick “Live CD/DVD”: In the “Attributes” section on the right side of the Storage settings, find the “Live CD/DVD” checkbox and tick it. This setting can sometimes help with boot processes from ISO images.

VM Processor Settings

After making these changes, click “OK” to save the settings. Start your virtual machine and check if the “product key” error is resolved.

3. Download a Fresh ISO File and Create a New VM

A corrupted ISO file is a common culprit for installation issues, including product key errors. If your ISO file is damaged or incomplete, it can lead to various problems during the Windows setup process. Downloading a new ISO file from the official Microsoft website and creating a fresh virtual machine can often bypass these issues.

Steps for New ISO and VM Creation:

  1. Download a New ISO File: Go to the official Microsoft website and download a fresh copy of the Windows ISO file you intend to install. Ensure you are downloading the correct version and edition of Windows that you have a valid product key for.

  2. Create a New Virtual Machine: In VirtualBox Manager, click on the “New” button to create a new virtual machine. Follow the on-screen prompts to configure the basic settings for your VM (name, operating system type and version, memory size, etc.).

  3. Defer ISO Selection During VM Creation: When you reach the step where you are asked to select the ISO file, do not select it at this stage. Proceed with creating the virtual machine without specifying an ISO file initially.

  4. Access VM Settings After Creation: Once the new VM is created, right-click on it and select “Settings.”

  5. Attach the New ISO in Storage Settings: Go to “Storage” then “Attributes.” Under the “Controller” section (e.g., “IDE Controller”), you should see an empty “CD/DVD-ROM” device. Click on the Disk icon next to it (it looks like a CD).

  6. Choose Disk File: From the dropdown menu that appears, select “Choose a disk file.”

  7. Navigate and Select the New ISO File: A file explorer window will open. Navigate to the location where you saved the newly downloaded Windows ISO file. Select the ISO file and click “Open.”

  8. Start the Virtual Machine: Click “OK” to save the settings and then start the virtual machine. The VM should now boot from the newly attached ISO file, and you can proceed with the Windows installation process.
