[solved] problems updating 1.5.1 to 1.6

Hi all,
i just tried yo update my 1.5.1 to 1.6 through “one click” update but it failed, i had a blank page

i tried to loose any restriction i could have put in my setup, eg in the .htaccess (allow from all), in the vhost conf (max memory 256MB, show errors), then commented "$config[‘driver_options’][MYSQLI_OPT_LOCAL_INFILE] = true; " in core/db/adapter/mysqli.php as i was seeing (only launching upgrade from the CLI) a related error and in this forum that was suggested

now i got another error:
“Fatal error: Maximum execution time of 30 seconds exceeded in E:\htdocs\piwik\piwik\libs\PclZip\pclzip.lib.php on line 3725”

what can i do to sove this and mysqli error, and succeed with the upgrade?

I know i can manually upgrade but wish to find wat’s wrong here

Thanks

in a flash of inspiration, i tried to also disable php safe_mode, and it worked, kinda.
in fact it was a 2 click update (:P) because one id for piwik download and one for the db upgrade
