Solution

This is usually caused by either a corrupt network connection entry, or too many interfaces entries in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network registry key.

Thankfully Microsoft have identified this as a problem and have a tool for fixing it, download the ifcleanup tool. (There is an x86 and an x64 bit version in that zip file run the one appropriate for the affected system).

How to Tell if Windows is 32 or 64 bit 

Open a command window (run as administrator) and run the ifcleanup executable.

2. Then retry to install the AnyConnect client.
