Fixing Speedify Virtual Adapter Not Present Error

If you see the error "The Speedify Virtual Adapter is not present" on Windows, it usually means the Speedify driver did not install properly. This article walks you through the steps to fix it.

Let's Get Started

Step 1: Reboot and Re-run the Speedify Installer

Sometimes another process on Windows is locking a file that the Speedify driver needs during installation. A reboot clears those locks.

1. Restart your computer.
2. Once it's back up, run the Speedify installer again.
3. After installation completes, launch Speedify and check whether the error is still appearing.

If the error is gone, you're all set. If it's still showing up, move on to Step 2.

Step 2: Check That the Required Windows Services Are Enabled

Speedify's driver depends on several built-in Windows services to install correctly. If any of these services are disabled, the driver won't install. Here's how to check them.

1. Open the Services screen. You can do this by pressing Windows Key + R , typing services.msc , and pressing Enter. You can also search for services.msc in the Start Menu, or open it from Task Manager under the Services tab.
2. In the Services list, locate each of the following services and make sure none of them are set to Disabled:
   • Device Install Service (Windows 8 and above only)
   • Device Setup Manager (Windows 8 and above only)
   • Plug and Play
   • Windows Management Instrumentation (WMI)
3. To check a service's status, double-click it. The Startup type dropdown should be set to Automatic or Manual, not Disabled. If it's Disabled, change it to Manual and click OK.
4. Once you've confirmed all four services are enabled, run the Speedify installer again.

You should see Speedify launch without the virtual adapter error after reinstalling.

Step 3: Check for Group Policy Restrictions (Corporate Computers)

Some system configurations, most often on corporate or managed computers, include policies that prevent new drivers from being installed. If you're on a work-issued machine and the steps above didn't help, your IT administrator may need to approve or assist with the Speedify installation.

Reach out to your system administrator and let them know that Speedify requires permission to install a network driver on the device.
