Cisco VPN Install Error 27850

One of my clients recently had an issue with their MYOB AO software, which requires a Cisco VPN client to be installed to complete certain tasks.
For some reason, it had removed itself, and when attempting to reinstall manually, I encountered the following error in Windows 7 x64:
Error 27850. Unable to manage networking component.  Operating system corruption may be preventing installation.
The long and short of it is a registry edit.
Locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters
Default: 8
Maximum setting: 14

I have bumped this up to 14 for my client, and it's now successfully working.
