VPN Client will not install

Greetings,

Trying to install VPN clinet ver. 5.0.07.0290 on WinXP box.

Gets to a certain point then errors out with

Error 27850.  Unable to manage network component.

Operating system corruption may be preventing installation.

I asked this question here before - and received answers instructioning me to uninstall the client.

That canot be done since there's no installed item within Add or Remove Programs to point to uninstall.  I've deleted the folder that's created, but it makes no difference - install stops at the same point each time.

Any other ideas?

Re: VPN Client will not install

Is your Windows XP 32-bit or 64-bit?

There are 2 version of VPN Client 5.0.07.0290:

32-bit: vpnclient-win-msi-5.0.07.0290-k9.exe

64-bit: vpnclient-winx64-msi-5.0.07.0290-k9.exe

Please kindly make sure you use the right software.

Here are steps that will help with the uninstallation:

1)    Remove the VPN Client (any version) from the machine using the MSI cleanup tool
http://support.microsoft.com/kb/290301

Upgrade the DNE using this link of Deterministic Networks
http://www.deterministicnetworks.com/support/dnesupport.asp

Run the WINFIX application and then the DNE upgrade.

2)    Take a backup of the registry.
3)    From your desktop, go to Start > Run and type regedit.
4)    Remove the following keys:

a) Go to HKEY_LOCAL_MACHINE > SOFTWARE > Cisco Systems > VPN Client.
b) Go to HKEY_LOCAL_MACHINE > SOFTWARE > Deterministic Networks and remove the keys.
Note: Sometimes the system will not allow for the removal of this key.

c) Go to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Uninstall >{5624c000-b109-11d4-9db4-00e0290fcac5}.
d) Delete all the old Deterministic NDIS Extender (DNE) files: any file starting with DNE as all are files coming along with VPN Client installations.

dne2000.sys from %SystemRoot%\system32\drivers
dne2000m.inf and dne2000m.pnf from %SystemRoot%\inf

e) The Original Equipment Manufacturers (OEM) enumeration of the dne2000.inf and dne2000.pnf files.

The OEM enumeration .inf file is a file called "oem (some numeric value).inf."
For example, oem2.inf and oem2.pnf.

Note: Be careful to remove only OEM files from the DNE.

dneinobj.dll from %SystemRoot%\system32. You may need to reboot before this file can be removed.

f) Delete the following file: cvpndrv.sys from %SystemRoot%\system32\drivers

5)    Reboot the machine

6)    Find for the CSGina.dll file in the system32 folder rename it to CSGina.old

7)    Reboot the machine

8)    Disable any firewall if any is installed.

Hope that helps.

Re: VPN Client will not install

Greetings,

Sorry - just now got time to try your steps.

Verified I've been using the correct client install for 32-bit

Ran msiccu2.exe (MSI cleanup tool) and could not locate any instance of the VPN client.

Deleted the Cisco VPN client folder.

Ran WINFIX

Then ran DNE Upgrade.

     Here's where I ran into this:

          'msiexec.exe has encountered a problem and needs to close'

After closing the error message - it comes back that the upgrade was successful.

Attempted to locate registry keys and files you listed - found some and not others.

Tried the install again ...............  Success!! 

Thanks for all of your assistance

Re: VPN Client will not install

I tried all your steps, but I still receive error 27850 when trying to install VPN Client 5.0.06.0160.    I have a shiny new computer with Windows 7, 64 bit OS.

There is nothing to uninstall on my computer and I did not have the registry keys that should have been deleted.

Any suggestions?

Re: VPN Client will not install

This was also answered in https://supportforums.cisco.com/message/3075095

In essense, the number of filters allowed on a network connection is 8 by default.  Increase this and the issue is resolved.  This fixed my issue without having to download some silly .exe to change too many things with your network setup.

The maximum number of network  filter drivers in Windows 7 is 14.

By default, it is set to 8

Can be increased to 14 in the the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters
