System Requirements For Cisco AnyConnect Client (3.1)

This page includes information for Windows, Mac & Linux Installations

iPhone/iPad and iTouch Support

NOTE: Before installing the Cisco AnyConnect VPN Client you will need Admin rights to your machine. You may have to arrange this through your relevant local IT support.

AnyConnect 3.1 installations can coexist with other VPN clients, including IPsec clients, on all supported endpoints; however, we do not support running AnyConnect while other VPN clients are running.

AnyConnect does not support virtualization software, such as VMWare for any platform or Parallels Desktop for Mac OS.

Microsoft Windows Support

To start AnyConnect with WebLaunch, use Internet Explorer 6.0 or later or Firefox 3.0+, and enable ActiveX or install Sun JRE 1.4+. Users of x64 (64-bit) Windows versions supported by AnyConnect must use the 32-bit version of Internet Explorer or Firefox to use WebLaunch. At this time, Firefox is available only in a 32-bit version.

Windows Compatability

  • Windows 10
    • AnyConnect 3.1MR10 (3.1.10010) and later are compatible with Windows 10 official release. Technical Assistance Center (TAC) support will be available beginning on 7/29/2015.
    • For best results, we recommend a clean install of AnyConnect on Windows 10 system and not an upgrade from Windows 7/8/8.1. If you are planning to perform an upgrade from Windows 7/8/8/1 with AnyConnect pre-installed, make sure that you first upgrade AnyConnect prior to upgrading the Operating System. The Network Access Manager module must be uninstalled prior to upgrading to Windows 10. After the first upgrade is complete, it can be re-installed on the system. You may also choose to fully uninstall AnyConnect and re-install one of the supported versions after upgrading to Windows 10.
  • Windows 8, 8.1 & Update 1 x86 (32-bit) and x64 (64-bit)
    • Windows RT is not supported
    • AnyConnect requires a clean install if you upgrade from Windows 8 to Windows 8.1
  • Windows 7 x86 (32-bit) and x64 (64-bit)
    • AnyConnect requires a clean install if you upgrade from Windows XP to Windows 7
    • Compatible with 3G data cards which interface with Windows 7 via a WWAN adapter
  • Windows Vista x86 (32-bit) and x64 (64-bit)
    • AnyConnect requires a clean install if you upgrade from Windows XP to Windows Vista

Please note, Windows XP and IE 8 are no longer supported by Microsoft following end of extended support after 8th April 2014, although compatible, this will not be supported

If you intend to upgrade your Windows installation, manually uninstall AnyConnect first. After the upgrade, reinstall it manually or by establishing a web-based connection to to install it. Uninstalling before the upgrade and reinstalling AnyConnect afterwards is necessary because the upgrade does not preserve the Cisco AnyConnect Virtual Adapter.

AnyConnect Support for Windows 8.x

  • AnyConnect support for Windows 8.1 Patch 1 was added in 3.1.05170.
  • AnyConnect support for Windows 8.1 32-bit and 64-bit was added in AnyConnect 3.1.04072.
  • AnyConnect support for Windows 8 32-bit and Windows 8 64-bit operating systems was added in 3.0.11042 and later versions (for 3.0.x versions) and 3.1.02026 and later (for 3.1.x versions).

Limitations to AnyConnect Support for Windows 8.x

  • Upgrading to Windows 8.1 requires you to uninstall AnyConnect, and reinstall it after your Windows upgrade is complete.
  • AnyConnect is not supported on Windows RT. There are no APIs provided in the operating system to provide this functionality. Cisco has an open request with Microsoft on this topic. Customers who want this functionality should contact Microsoft to express their interest.
  • Other third-party product’s incompatibility with Windows 8 prevent AnyConnect from establishing a VPN connection over wireless networks. Here are two examples of this problem:

– WinPcap service “Remote Packet Capture Protocol v.0 (experimental)” distributed with Wireshark does not support Windows 8 . To work around this problem, uninstall Wireshark or disable the WinPcap service, reboot your Windows 8 computer, and attempt the AnyConnect connection again.

– Outdated wireless cards or wireless card drivers that do not support Windows 8 prevent AnyConnect from establishing a VPN connection. To work around this problem, make sure you have the latest wireless network cards or drivers that support Windows 8 installed on your Windows 8 computer.

  • AnyConnect is not integrated with the new UI framework, known as the Metro design language, that is deployed on Windows 8; however, AnyConnect does run on Windows 8 in desktop mode.
  • AnyConnect 3.1.01065 and AnyConnect 3.0.10055, and later AnyConnect 3.0 releases, provide “toast notifications.”
  • Verify that the driver on the client system is supported by Windows 8. Drivers that are not supported by Window 8 may have intermittent connection problems.
  • For Network Access Manager, machine authentication using machine password will not work on Windows 8 / Server 2012 unless a registry fix described in Microsoft KB 2743127 ( is applied to the client desktop. This fix includes adding a DWORD value LsaAllowReturningUnencryptedSecrets to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa registry key and setting this value to 1. This change permits Local Security Authority (LSA) to provide clients like Cisco Network Access Manager with the Machine password. It is related to the increased default security settings in Windows 8 / Server 2012. Machine authentication using Machine certificate does not require this change and will work the same as it worked with pre-Windows 8 operating systems.

Windows Requirements

  • Pentium class processor or greater.
  • 100 MB hard disk space.
  • Microsoft Installer, version 3.1.


The following sections show the Linux distributions and requirements.

Linux Distributions

  • Red Hat Enterprise Linux 5 Desktop.
  • Ubuntu 9.x and 10.x.
    We do not validate other Linux distributions. We will consider requests to validate other Linux distributions for which you experience issues, and provide fixes at our discretion.

Linux Requirements

  • x86 instruction set.
  • 32-bit or biarch 64-bit processor.
  • 32 MB RAM.
  • 20 MB hard disk space.
  • Superuser privileges are required for installation.
  • libstdc++ users must have or higher, but below version 4.
  • Java 5 (1.5) or later. Iced Tea is the default Java package on Fedora 8. The only version that works for web installation is Sun Java. You must install Sun Java and configure your browser to use that instead of the default package.
  • zlib.
  • gtk 2.0.0,
    gdk 2.0.0,
    libpango 1.0.
  • iptables 1.2.7a or later.
  • tun module supplied with kernel 2.4.21 or 2.6.

AnyConnect SMC 3.0 reportedly runs on 64-bit Linux, although we do not support it.

Mac OS X

AnyConnect 3.1 supports the following versions of Mac OS X: (32-bit or 64-bit)

• Mac OS X Mountain Lion (v10.8)

• Mac OS X Mavericks (v10.9)

• Mac OS X Yosemite (v10.10)

AnyConnect Support for Mac OS X

  • Mac OS X 10.5 is no longer supported. AnyConnect 3.1 will not install on this platform.
  • Mac OS X 10.6, and 10.7 are no longer supported.

AnyConnect requires 50MB of hard disk space.

Mac OS X Mountain Lion (v10.8) introduces a new feature called Gatekeeper that restricts which applications are allowed to run on the system. You can choose to permit applications downloaded from:

  • Mac App Store
  • Mac App Store and identified developers
  • Anywhere

The default setting is Mac App Store and identified developers (signed applications). AnyConnect release 3.1 is a signed application, but it is not signed using an Apple certificate. This means that you must either select the Anywhere setting or use Control-click to bypass the selected setting to install and run AnyConnect from a pre-deploy installation.

Users who web deploy or who already have AnyConnect installed are not impacted. For further information see:
