This article will provide information on how to remove the LinkManager adapter from the registry. This is the
last resort of troubleshooting, when you suspect that the adapter have been damaged by another software.
LinkManager Adapter Removal
A special scenario can occur if the LinkManager has been installed as a NON-Administrator, or the LinkManager Adapter installation has been stopped by an AntiVirus program or other security software. Uninstalling and re-installing does not work either.
In this case, you need to remove the faulty adapter first. Please ensure that no Anti Virus scanners are enabled, and preferably all VPN clients should be stopped.
Stop the LinkManager processes
Stop the LinkManager Process by right clicking the taskbar and selecting "Task Manager":
In the Task Manager, select the "Processes" tab, click "Image Name" to sort by letter, and find "LinkManager.exe".
Right click it and select "End Process". If "LinkManager.exe" does not exists, just ignore and find the next process below.
Do the same for all processes starting with "VBox...".
The faulty adapter needs to be removed from registry, and there could be more than one, so we need to remove them all.
Click the "Start Menu" button and select "Run". Type "Regedit" and press ENTER.
Click "Computer" and select "Edit -> Find...":
Type "LinkManager Adapter" in the search box, and click "Find Next":
When the string is found, it will be found in "Connection" key. Right click the one immediately above it (long number), and select "Delete".
Continue doing this process by selecting "Edit -> Find Next", until all Adapters has been deleted and the string cannot be found anymore.
Close the Registry Editor.
Next, all the Network Adapters in Device Manager needs to bee deleted.
Click the "Start Menu" button. Right click "Computer" and select "Manage":
Select "Device Manager":
Expand "Network adapters" and right click all "VirtualBox TAP Adapter..." and select "Uninstall".
Do not choose to Delete the driver. Click "OK".
Do the same for all adapters starting with "VirtualBox TAP Adapter...".
Finally try to start the LinkManager again.
