1- How to Repair the installation to troubleshoot Cisco VPN

The first thing you need to do is repair the installation. Many third-party applications run into problems after major operating system updates. Therefore, it is always recommended that you update them again after updating the operating system.

It is even recommended that you delete various errors after updating. Of course, if you haven’t removed Cisco VPN before updating, you’ll need to repair the software installation.

If you don’t know how to repair Cisco VPN, follow these steps:

A. In the Windows Search section, type Control Panel and select it.

C. Click on the Cisco system VPN client and then click Repair.

D. Follow the steps until the installation is completed.

2- How to Allow the VPN to communicate freely in the firewall

System updates can change the operating system settings to default. This can also affect Windows Defender settings. If this happens, there is a possibility of this problem for all applications that need to send traffic from the firewall. That’s why we recommend that you check the settings and make sure that the application is allowed to pass Internet traffic:

A. In the Windows Search section, type Allow an app to display the Allow an app through Windows Firewall option, and when this option is found, select it.

B. Click Change Settings.

C. Make sure Cisco VPN is on the list and is allowed to pass traffic through the firewall. If Cisco VPN is not available, click Allow another app to add this option to the list of authorized apps.

D. Check both Private and Public options.

E. Apply the changes and then open Cisco VPN.

 

3- Manipulation in the registry

Like all other VPNs available, Cisco VPN requires a Virtual Network Adapter. Failure of this device is another common occurrence that is indicated by error code 442. The first thing you need to do is check the virtual network card driver in Device Manager.

To do this, follow these steps:

A. Click Start and open Device Manager.

B. Open the Network Adapters section.

C. Right-click Virtual Adapter and update it.

D. Reset the computer.

If the problem persists, you must manipulate the registry. This will probably solve the problem completely. You need admin access to make changes to the registry.

Note that if you make changes to the registry, do so carefully, because if you make a mistake in registering the changes in the registry, it can lead to system errors.

How to change the registry and repair Cisco VPN

A. Write regedit and open Registry Editor.

B. Enter the following path in the Address bar section and then press Enter:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCVirtA

C. Right-click the DisplayName button and select Modify.

D. In the Value Data section, make sure there is Cisco Systems VPN Adapter text. For 64-bit versions, this text is in the form of Systems VPN Adapter for 64-bit Windows.

E. Save the changes and run Cisco VPN again.

4- How to Reinstall the Cisco VPN Software

Finally, if none of the above methods work, the last resort is to uninstall and reinstall the software. Of course, this installation should be such that you delete all the existing files and do not keep any settings in the operating system, which requires the existence of a third-party software such as Ashampoo uninstaller.

Follow these steps to reinstall Cisco VPN:

A. Enter the Control Panel and open Uninstall a program.

 

How to Reinstall the Cisco VPN Software

 

B. Delete Cisco Systems VPN Client.

C. Ashampoo Uninstaller (or run any third-party cleaning software)
