I've tried various methods to install Cisco VPN on a Windows 7 64-bit machine. I keep getting the same error:
Error 27850. Unable to manage networking component.
Operating system corruption may be preventing installation.
Awesomely evil. What bothers me is that one of my co-workers, who has an image of my machine, who also saw this problem, ran a particular installer and it worked for him. But it didn't work for me.
I have tried the following Cisco VPN client installers (based on the EXE file names):
- x64 client
- x64 5.0.07.0240 - k9 - BETA client
- Windows 7 client (wasn't compatible with x64)
They all give me the same error (minus the latter, which wouldn't run). I'm also suspecting this may be from a partial uninstall which may not have been properly purged (and lead to restore point corruption). Both of those issues were resolved, but maybe there are some dregs left in my system.
