I have been able to get the Cisco VPN client, the one which goes by the name vpnclient-winx64-msi-5.0.07.0440-k9, on Windows 8.1 x64 machines. Now I have a Windows 10 TP machine.
Has anyone gotten this client to install on 10? I get the following:
Error 27850. Unable to manage networking component. Operating system corruption may be preventing installation.
Ring any bells? I also cannot get the Citrix DNE installed. Very similar message.

I have a slightly different version: 5.0.07.0290 vs 5.0.07.0440. I got this client working with Windows 10 earlier this year and then just recently a Windows Update broke this again. Here's what I did to fix it:
I checked the registry for the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA
The key didn't exist. I then went to:
Control Panel > Programs and Features > Cisco VPN Client
Then selected repair, and rebooted.I checked the key again and it existed. I replaced the Display Name null string value (REG_SZ) that listed:
@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows
with the new value:Cisco Systems VPN Adapter for 64-bit Windows
. I rebooted and it worked again.To start from an uninstalled state, here's what I did in the past:
If you don't see the client start, check services.msc or
Control Panel > Services
and ensure the serviceCisco Systems, Inc. VPN Service
is running.As for your error, make sure you have a recent Windows 10 update and if it still isn't working possibly run the installer in compatibility mode for Windows 7. Another thing to try is a system file check. From an elevated command prompt, or powershell session, run the command:
sfc /scannow
