- [faq1] Who is "Igor Pavlov", whose name appears in the VPN Client installer?
Igor Pavlov is the author of the program 7-zip, which we use to create a self extracting installer for the VPN Client. 7-zip is an open source packager with a very high compression rate and is mainly published under the GNU LGPL Lizenz.
- [faq2] The VPN Client cannot be installed after a previous removal and demands that the previous VPN Client has to be uninstalled.
Only make changes in the registry if you know what you are doing! We do not take responsibility for damage done to your computer.This error message is created because of an uncomplete removal. Even after deleting the Cisco VPN Client folder (%ProgramFiles%\Cisco Systems\VPN Client), an installation is not possible, because the registry entries of the VPN Client are still left over. Exactly which entries are left is hard to describe in a FAQ; the following troubleshooting is possible:
- To find the resgistry entries to which the VPN Client installation is referring, start the ProcessMonitor from SysInternals.com. Afterwards, try the installation again and pay attention to the displayed registry entries (show registry activity). When you see an entry that needs to be deleted, mark the entry and click Ctrl-J to get to the according entry in the registry, where you can delete it.
- Alternatively you can directly use the registry editor with Start → run → regedit. Search for vpn and/or cisco and delete the entries, if necessary.
- [faq3]The Cisco AnyConnect client cannot be installed: The installation is aborted without an error message.
If the installation is automatically aborted without an error message, but other programs can be installed without any issues, your device might have trouble invoking the Windows Installer msiexec. To check this, you first need to find the file path for the msiexec.exe. Click the Windows key, search for msiexec.exe and click on Open File Location. In normal circumstances, the file path is as follows: C:\Windows\System32. Afterwards, you need to check if the previously identified file path is present under Advanced System Settings → Environment Variables → System Variables → Path → Edit. If it's not present, add the file path via New → "File Path" → Ok. Finally, restart your computer as follows and run the installation program again: Windows key + R → shutdown /f /r /t 0 → Ok.
- [faq4] The VPN connection on Windows Vista takes very long to get established.
According to the Ciscos release notes for Version 5.0.03.0390 of the Windows VPN Client, this is not a bug, but due to additional processes that need to be transitioned in Windows Vista to activate the VPN adapter.
"VPN Client takes longer to connect on Vista compared to XP. This is due to new features in Vista."
- [faq5] The Cisco AnyConnect Client prints the following error: "Could not create interprocess communication depot".
Deactivate the "SharedAccess" service:
over the graphical UI:
- Start ⇒ run ⇒ services.msc
- Stop "Internet Connection Sharing" (a.k.a. "Gemeinsame Nutzung der Internetverbindung") and set the start type to manual.
Alternatively, you can run the following two commands with administrative rights in the console:
- sc stop "SharedAccess"
- sc config "SharedAccess" start= disabled
- [faq6] The Cisco AnyConnect Client prints the following error: "VPN Service not available".
Check, whether the Software "RapidBoot Shield" / "RapidBoot HDD Accelerator" is installed. It is incompatible with the AnyConnect Client and needs to be uninstalled or deactivated.
- [faq7] The establishing of the connection stops with the message "VPN Service not available. The VPN agent service is not responding. Please restart this application after a minute".
The AnyConnect VPN service under Windows doesn't start automatically. The error "VPN Service not available. The VPN agent service is not responding. Please restart this application after a minute." means that the service could not be started successfully. This may be caused by a boot-speed-up software, which changed the starting order of the Windows services, so that some services may not be started successfully. Programs which caused this error in the past were e.g. Lenovo Rapid Boot (also: RapidBoot HDD Accelerator, RapidBoot Shield). After the deinstallation of the accoring boot-speed-up software, the problem should be fixed. (Windows XP: Control Panel -> Software, Windows Vista/7/8: Control Panel -> Programs).
- [faq8] Where does the user account ciscoacvpnuser come from?
During the installation of the Cisco AnyConnect, a restricted user account (ciscoacvpnuser) is created for the management tunnel feature. This account is used by AnyConnect to enforce the principle of least privilege when initiating a management tunnel connection. This account does get removed during AnyConnect uninstallation. [more]
Since the TUHH does not use this function at all, the user account ciscoacvpnuser can be safely deleted.
- [faq9] Where is the pre-configured TUHH VPN profile?
The settings for the TUHH VPN server are stored in an XML configuration file after the Cisco AnyConnect installation at: %ProgramData%\Cisco\Cisco AnyConnect Secure Mobility Client\Profile\TUHH.xml (just type in the address line of the explorer).
