Installing Cisco VPN Client on Windows 7
Sebastian Atar
I'm in my second year with C/D/H and look forward to using my 10+ years of IT experience, along with my MBA background in finance and lean operations to solve business problems.
Most recently, this has involved using Microsoft Office SharePoint Server to enable collaboration and sharing of information, as well as Novell Identity Manager to simplify management of user accounts.
When not working, I enjoy spending time with my wife and son. We love visiting family in Seattle and New York. When not traveling, we pass time reading, gardening and BBQ-ing with family.

I recently installed Windows 7 Beta (build 7000). I’ve been impressed with this new iteration of Windows. The GUI is nearly identical to Vista; however, the first thing I noticed is the improved performance. Needless to say I am very happy with it, as my clients, friends and family will attest. If you have held off from installing Vista because of “horror” stories about performance, give Windows 7 a shot. I am confident you will be equally impressed, just search the web and you will find many articles touting improvements, etc.
However…we are here to talk about the Cisco VPN Client.
Running “beta” software you tend to open yourself up to issues that have yet to be resolved, bugs, etc. Today I ran into an interesting issue, right in the middle of trying to get some work done. I installed the Cisco VPN Client (version 5.0.03.0560) and upon rebooting was greeted with a lovely BSOD. My laptop would be stuck in a continual cycle of rebooting and BSOD, until I repaired the install which rolled back the Cisco VPN installation.
Note: I am also running the Citrix XenApp Plugin for Hosted Apps (version 11.0.0.5357)
Here is how I managed to get past this and get back to work:
- Uninstall previous versions of Cisco VPN Client
- Reboot
- Download and run the DNE Fix from Citrix
- Reboot
- Download and install the Citrix DNE Update
- Reboot
- Take ownership of and assign yourself “Full Control” permissions to the following files:
c:\windows\system32\drivers\ndis.sys
c:\windows\system32\drivers\en-us\ndis.sys.mui - Delete the above files
- Install the Cisco VPN Client (documentation I have found asks for 5.0.4.0300 or better, as you can see I had success with 5.0.03.0560)
- Reboot (Windows will repair itself)
- Import your *.PCF files
- Connect
…now back to work!

No, it was actually this blog post (and subsequent discussion) that got me going in the right direction:

But I see you had the same issue. Also, this is a little outdated now since as your update notes v5.0.05.028 resolves this issue.
