At least I did. I had to remove the ndis.sys file after installing the VPN client error 1721 and before rebooting. Then when you reboot Win 7 will repair this file and you are prompted to reboot once again and now it will work. /WW Wictor - Thursday, January 15, 2009 2:12:52 PM 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. 2. Reboot 3. Take error 1721 windows ownership and delete ndis.sys (in c:\windows\system32\drivers). 4. Take ownership and delete ndis.sys.mui (in c:\windows\system32\drivers\en-us). 5. Install Cisco VPN Client 5.0.04.0300. 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. JoshP - Friday, January 16, 2009 5:06:46 AM To further elaborate on steps 6 & 7; 6. Insert your Windows 7 install disc. 6a.

One thing you can try is to open up a command prompt with Run as Administrator option. Then run your setup program using msiexec.exe. The syntax for running it would be. msiexec /i YourAppName.msi. Other than that you could try disabling UAC. Hope this helps Don May 22 '09 #2 reply P: 68 Kosal Ok Don Let me try first. thanks you for your help.
