However, while using OpenVPN with Windows, some people struggle with Windows Route Add Command Failed [Adaptive]: Returned Error Code 1, but they don’t know how to resolve the issue. For this purpose, we have the information for fixing this error!
How To Fix Windows Route Add Command Failed [Adaptive]: Returned Error Code 1
1. Microsoft Issues
Hey, before you step into the troubleshooting methods, there are high chances that Microsoft is imposing security measures. In addition, if you aren’t sure if the error is actually by Microsoft, it’s best that you get in touch with customer support. This is because, in some cases, Microsoft adds new updates that might not be compatible with OpenVPN.
2. Administrator
To begin with, the users need to ensure that you are logging into OpenVPN as the administrator. However, some people are still getting the error if they are already running the administrator. For this purpose, one needs to select the OpenVPNGUI.exe and right-click on the “run as administrator” option and it will help resolve the error.
On top of everything, you should only run OpenVPN as administrators when you are logged in to the system. In addition to this, ensure the OpenVPN is running on the highest privileges to ensure everything works optimally!
3. Access Denied
If you are using Windows 7 or Windows Vista, there are chances of access denied issues on the route.exe command. So, if you are using the Windows variants as we mentioned, you need to run OpenVPN with the elevated privileges.
4. Updates
In some cases, such errors and glitches persist when you aren’t using the latest version of OpenVPN. Especially when you are using OpenVPN on a Windows system, you need to ensure that OpenVPN is running on the latest update. As for now, the latest version is 2.3.11, and we suggest downloading it for streamlined working.
5. TAP-Windows Adapter V9
While using Windows, the users actually have a higher privilege to take things in their hands, which is obviously better for fixing this issue on their own. With this being, open the control panel on your system and tap on networks and the internet. Then, tap on the network and sharing center and scroll down to change settings for the network adapter. This is usually available on the left column.
Then, click on the TAP-Windows Adapter V9, and it will fix the complete configuration with the network. Once the configuration is complete, start the OpenVPN again, and the error will be gone!
6. Local Admin
To be honest, this issue usually happens when you are running OpenVPN as the local administration rather than the member. If this is the case, uninstall OpenVPN from your system as the local admin. Then, log in with the user credentials and download OpenVPN again. When the UAC page opens up, enter your local admin password. As a result, the group will be created, and you need to add the user to this group.
