Fix Visio LTSC Activation Failure After Reinstalling Windows

Product: Microsoft Visio LTSC
Device & OS: Windows
Scenario: Activating a perpetual Visio LTSC license on a freshly reinstalled Windows computer alongside a subscription-based Microsoft 365 E3 installation.
Observed behavior: Visio LTSC fails to activate, likely due to conflicting activation data from the existing Microsoft 365 E3 applications.

Before you start

Ensure you are logged into Windows with Administrator privileges and have your Visio LTSC volume license key ready before proceeding with the license cleanup.

Solution 1Recommended

Clear Conflicting Office Licenses Using OSPP.VBS

Use the built-in Microsoft script via Command Prompt to manually remove conflicting Microsoft 365 or old Office activation data, allowing Visio LTSC to activate.

When installing Visio LTSC alongside Microsoft 365, the system can confuse the subscription and perpetual licenses. Running the Software Protection Platform script (ospp.vbs) forces Windows to forget the conflicting key so you can perform a clean activation.

Open Command Prompt as Administrator

Click the Windows Start menu, type 'cmd' in the search bar, right-click on 'Command Prompt', and select 'Run as administrator'.

Locate the OSPP.VBS Script

Navigate to your Office installation folder. Type 'cd C:\Program Files\Microsoft Office\Office16' and press Enter. If you encounter an error, try the 32-bit path by typing 'cd C:\Program Files (x86)\Microsoft Office\Office16'.

Identify the Conflicting Key

Type 'cscript ospp.vbs /dstatus' and press Enter. This will display all installed Office licenses. Locate the entry causing the conflict and note the last 5 characters of the installed product key.

Remove the Product Key

Type 'cscript ospp.vbs /unpkey:XXXXX' (replace XXXXX with the 5 characters you found) and press Enter to uninstall the product key.

Restart and Reactivate

Restart your computer, open Visio LTSC, and follow the standard activation prompts using your Volume License key.

Clear Conflicting Office Licenses Using OSPP.VBS

Command Prompt Directory: You must run the cscript command directly from the folder containing the ospp.vbs file, otherwise Windows will return a 'file not found' error.

Solution 2

Contact Microsoft Volume Licensing Support

If manual script cleanup fails to resolve the activation block, you may need backend support from Microsoft's volume licensing team.

Frequently Asked Questions

Why does Visio LTSC conflict with Microsoft 365?

Microsoft 365 utilizes a subscription-based user-level activation (Click-to-Run), while Visio LTSC uses a perpetual volume license. Installing both on the same machine can cause the local activation service to confuse the credentials, requiring manual license cleanup.

Where can I find the OSPP.VBS script on Windows?

The script is located in your core Office installation folder. For a 64-bit installation of Office on 64-bit Windows, check 'C:\Program Files\Microsoft Office\Office16'. For a 32-bit installation on 64-bit Windows, look in 'C:\Program Files (x86)\Microsoft Office\Office16'.

What should I do if OSPP.VBS returns an 'Input Error'?

This error usually occurs if you are not running Command Prompt as an Administrator, or if your Command Prompt is not currently navigated to the exact directory where the ospp.vbs file is located. Use the 'cd' command to change directories before running 'cscript'.
