Now Windows will try to install the driver. Once the driver is installed, check if the problem still persists.


Solution 7 – Uninstall conflicting software

Several users reported that they were unable to run Hamachi on their PC due to their VPN client. Hamachi is a network tool, so it’s not uncommon for other network applications, such as VPN, to have issues with it.

Users reported that uninstalling their VPN fixed the problem, so you might want to try that. According to users, the issue was caused by Dell VPN client, but after removing it, the problem was completely resolved. If you want to remove all files associated with your VPN, we strongly recommended that you use a dedicated uninstaller such as Revo Uninstaller or IOBit Uninstaller to remove the problematic application.

After removing your VPN, the problem should be resolved and Hamachi will start working again. However, if you need a new VPN, you might want to try CyberGhost VPN.
