fuzzy Cisco VPN client software on Vista

/***
Feb 04, 2009 : the latest update: do 1 thing to fix "Error 442: Failed to enable virtual adapter" in Cisco VPN client by "Control Panel -> Network Connections: disable then enable the "local area connection".

Ignore my previous post, which works sometimes however.

It really became fuzzy and drove me mad tonight. I was supposed to VPN to office from home, then upload some files to Oracle metalink. As normal, I open Cisco vpn client, gave username/password when got prompted, but it just popped 442 error "442: failed to enable virtual adapter" after silent there 10 secs. What is that?

Google got a FAQ for me: "CISCO VPN Client Software on Windows Vista"  (http://geekswithblogs.net/evjen/archive/2007/01/01/102429.aspx),  very bad, solution in that did not work for me.

"Error 442: Failed to enable virtual adapter
Open Network and Sharing Center
Open Network Connection Manager
Enable the virtual adapter (“Cisco VPN Adapter”)
Right-click on it and select “Diagnose”
Select “Fix…”

If this doesn’t work
Run the following from ‘cmd’:
reg add HKLMSystemCurrentControlSetServicesTcpipParameters /v ArpRetryCount /t REG_DWORD /d 0 /f
Reboot

NOTE: If customer has UAC enabled, s/he must run ‘cmd’ as administrator.
"

I tried re-install it, something rotten behind , well, that was true  and always happened on windows, you know it…
not lucky enough, got more errors when remove current software, anyway, it gone. I encounter errors and had to terminated installation when install Cisco vpn client again, really weird , isn’t it? it was so fuzzy and I almost got mad after 2-3 times try.

I get "Brutal force" idea this time. go to registry, manually delete keys with ‘vpn’ in LOCAL_MACHINE**, rebooted, installed it again, woohoo!, worked this time my old friend. (I KNOW, messy registry always block installations on windows, no exception on Vista)

Now I have to go to my office pc and retrieve stuff for Oracle.
