ALOT of enterprise users are having issues with the native Cisco client running safely on a Windows 7 64-bit platform. A colleague of mine (Thanks Jonathan Schwartz!) Tipped me off to this potential work around. *** USE AT YOUR OWN RISK ***
How to (Successfully) Install Cisco VPN Client on Windows 7

I have tried many–many different ways to get the Cisco VPN client install on Windows 7–all resulting in BSOD (ndis.sys).  I have found the following procedure has worked 100% of the time on multiple hardware platforms (including VMware):

1.  Install Cisco DNEupdate. – see below

2.  Reboot

3.  Take ownership and delete ndis.sys (in c:windowssystem32drivers).

4.  Take ownership and delete ndis.sys.mui (in c:windowssystem32driversen-us).

5.  Install Cisco VPN Client

6.  Reboot

7.  Windows 7 will repair itself (should take a few seconds) and automatically reboot.

8.  Cisco VPN Client should work without any other tweaks.

Hope this helps.

To further elaborate on steps 6 & 7;

6. Insert your Windows 7 install disc.

6a. Restart into the Windows 7 install when prompted otherwise the OS will go into error recovery.

7. Select your language, time & currency and click ‘Next’.

7a. Click ‘Repair your computer’ at the bottom.

7b. Click ‘Next >’ to start the repairing the OS.

The Startup Repair wizard kicks in and works its magic. How long it will take to repair WILL vary
