If you are a user of Cisco VPN client then you may come across this error during either installation or when you try to uninstall the client:
This is usually due to a corruption in the Windows operating system configuration and can happen if you have more than one VPN client installed (or attempted install).
But, the fix is very easy. Simply go into your registry using regedit command and find the follow key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNetwork
From here you should now see a “Config” string. You should delete this string and reboot your machine.
After the install, try your install or uninstall and you should now notice that it works perfectly!

В связи с переходом на Windows 10 некоторые приложения отказываются устанавливаться и нормально работать. Именно так и случилось с VPN-клиентом Cisco, а точнее с последней выпущенной версией Cisco Systems VPN Client 5.0.07.0440. Здесь я предлагаю вам решение этой проблемы.
Установка VPN-клиента Cisco в Windows 10
После того, как вы распаковали дистрибутив, вы можете запустить один из двух файлов для установки: vpnclient_setup.exe или vpnclient_setup.msi. При запуске первого файла вы сразу получаете сообщение, что приложение установить невозможно и Cisco VPN Client не работает в данной версии Windows.
А если вы запустите файл vpnclient_setup.msi, то он даже начнёт установку, но сломается примерно посередине процесса во время настройки сетевых компонентов. У меня вылетела ошибка «Error 27850. Unable to manage networking component. Operating system corruption may be preventing installation».
Но решение есть. Сначала нужно установить последнее обновление DNE (Deterministic Network Extender), которое вы можете скачать с сайта Citrix отсюда. Скачивать нужно не всё, а только файл необходимые файлы: dneupdate.msi для 32-битных Windows или dneupdate64.msi для 64-битных Windows. Если при установке DNE у вас будут какие-либо проблемы, то рекомендуется удалить все программы, использующие DNE (такие как VPN-клиенты), затем воспользоваться утилитой очистки winfix.exe и повторить установку dneupdate.msi или dneupdate64.msi.
После установки обновления DNE можете повторить установку Cisco VPN-клиента. Запускать нужно файл vpnclient_setup.msi. У меня установка прошла успешно.
Настройка VPN-клиента Cisco в Windows 10
После создания подключения я попытался подключиться к серверу. Но получил ошибку «Reason 442: Failed to enable Virtual Adapter».
Эта ошибка происходит из-за того, что VPN-клиент не находит виртуальный адаптер сети (в моём случае Cisco Systems VPN Adapter for 64-bit Windows). Исправляется это так. Запустите редактор реестра (regedit.exe), найдите ветку HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCVirtA, в ней есть значение с именем DisplayName, которое содержит что то подобное: «@oem172.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows».
Поменяйте значение этого поля (контекстное меню «Изменить…» по правой кнопке мышки), чтобы осталось только «Cisco Systems VPN Adapter for 64-bit Windows» (для 32-битного VPN-клиента здесь должно остаться «Cisco Systems VPN Adapter»).
После этого попробуйте установить соединение снова (перезапускать VPN-клиент при этом не обязательно). У меня всё заработало без проблем.

I’ve just upgraded to Windows 10 and I’m trying to install vpnclient-winx64-msi-5.0.07.0440-k9. I’m running the install program as being compatible with Windows 7 (also tried XP). The install wizard opens and starts to run, but soon errors out: 27850.
I’ve found similar issues reported for Windows 7 and 8; however, none of the solutions seem related to this issue.
Has anyone experienced this in Windows 10 and found a solution?

Did little more research and found that I need to install DNE from Citrix.
Installed DNE and I was able to install VPN client without error. No restart required after DNE installation.
Worked fine for me, I can also connect to client using VPN.
