try to install windows update (kb971737), but I get the error

whenever I try to install this update I get error 80070020, I tried all (safe mode with network-clean boot-dissabeling antivirus and firewall, manual installation) nothing worked
My os: win vista ultimate sp2 64-bit
anti-virus: norton 360 v2 + windows deffender

Yes, I use ie8 you think if I UPGRDE TO NORTON 360 V3 COULD SOLVE this?

If you have installed (no upgrade to) N360 2010 v3.0, IE8 would be much more effective for you, but I suspect that this will not to solve the problem you experienced when you try to install KB971737, don't.

Here's what you could try though:

1. download the Norton Removal Tool, save it to your desktop: ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

2. close all open applications (that is, anything with an icon on the taskbar).

3. After completing some you have a copy of your handy product key, uninstall all Norton software (including LiveUpdate and everything Norton Add ons) via Control Panel | Programs | Uninstall a program (or Control Panel |) Programs and features, if you are using the classic view).

4 IMPORTANT! -Online activate Windows Firewall immediately after the restart.

NB: Now you're "working without a net": no to ANYTHING else online (for example, navigation; read E-mail; cat download other stuff) until you have completed step #8 below!

5. right click on the file that you saved in step #1 above, and then select run as administrator.  DO TAP not your keyboard until the race ends, then restart.

6. While N360 is no longer present on the computer, see if you can install KB971737 (and offered security critical updates) now.

7. now, to do a clean install of N360 2010 (using your product ID, if necessary) & restart: http://www.symantec.com/norton/support/kb/web_view.jsp?wv_type=public_web&docurl=20080514162318EN

TIP: Do not activate or install additional modules of Norton (for example, Norton Anti-Phishing) immediately.

8. manually and repeatedly run LiveUpdate until you get a prompt "no update more".
