SOLVED! Failed To Install Tap Adapter

If you run your VPN without administrative privileges, it’s only natural for you to failed to install TAP adapter and the best solution is to run the VPN as an administrator. If the issue persists, you should uninstall and reinstall the VPN, remove other VPNs, disable then enable your device, disable the firewall and reinstall Windows. Continue reading to learn what must be done to complete the TAP adapter installation. 

The Root Of The Problem

Corrupted Cache

In layman’s terms, cached data allows your PC to open the application quickly the next time you open them. Still, if the cache of your VPN app becomes corrupted, things could go haywire. Needless to say, in discussions about the failure to install TAP adapter, corruption of cached data is the number one suspect. 

Conflicting Software

You have multiple VPN applications on your Windows computer and they have their own TAP adapters? Then there is a chance that the applications would come into conflict with each other which leads to errors. On the bright side, if your computer failed to install TAP adapter due to conflicting software, there is no need to do much.


For your information, firewall is a network security system that uses previously established policies to monitor incoming and outgoing network traffic. However, it’s not uncommon for the firewall to overreact and classify the operation of apps like VPN as suspicious. If VPN is in the crosshair of firewall, the failure to install TAP adapter is one of the consequences. 

How To Tackle The Issue

Run As Administrator 

In the beginning, you should run your VPN app as admin and in compatibility mode.

  • Step 1: From the desktop, right-click the application’s shortcut then pick Properties.
  • Step 2: Go to the Compatibility tab, check the checkbox below Compatibility mode and select your Windows version via the drop-down menu.
  • Step 3: Check the checkbox beside Run as administrator then choose Apply and hit to save changes.
  • Step 4: Launch your application again

  • Step 1: Launch your web browser, visit the Microsoft website and download the Media Creation Tool.
  • Step 2: Once the download is complete, you will be prompted to run the Media Creation Tool so hit Run.
  • Step 3: Read all the terms and conditions then hit Accept.

How Does A VPN Work?

A VPN works by routing your device’s internet connection through a chosen VPN’s private server instead of your Internet Service Provider. VPN will connect you to a private server first then scramble data to make it difficult for third parties to track.

Can VPN Alter The Network Speed?

VPNs are known for increasing/reducing the speed of your network. If you are using servers far away from your location, you will have a slow connection. That is because data has a lot of distance to cover with bottlenecks and server points. The greater the distance between your location and the server you’re connecting to, the slower your Internet speed. VPN can speed up your connection when your internet service provider throttles connections.


  • As a precaution, refrain from using free VPN services.
  • Read reviews from previous users before proceeding to download or subscribe to a VPN service.
  • Need to save on money? Pay for an annual subscription rather than monthly plans.
  • Turn on your VPN when booking for rental and flight tickets to avoid high booking rates.
