Problem:
When trying to install Cisco AnyConnect on your Windows 7 64-bit system, you get the error: “The VPN client agent was unable to create the interprocess communication depot.”
Cause:
The Cisco AnyConnect install can fail if ICS (Internet Connection Sharing) is enabled for your computer, either system wide or on a network adapter that is configured to do ICS.
Solution:
You will need to disable ICS in order to use Cisco AnyConnect VPN. There are two ways to do this, and you will need to be an administrator of your computer to complete them.
1. To disable ICS on a single network adapter that you use to connect to the Internet:
- Click the Start button
- Click on Control Panel
- Click on View Network Status and Tasks
- Click on Change adapter settings
- Right-click the shared connection and choose Properties
- Click the Sharing tab
- Disable or uncheck the box next to “Allow other network users to connect through this computer’s Internet connection”
- Click OK
- Reboot your computer
2. To disable all ICS system wide:
- Click the Start button
- Type “services.msc” and press ENTER
- Double-Click on Internet Connection Sharing (ICS)
- Change “Startup Type” to Disabled
- Reboot your computer
Once you have completed these steps, attempt a full reinstall of Cisco AnyConnect VPN software.
