I'v tried to construct the piwigo site on my pc but there's an error to create table in database.
my system is win7 , with iis75 , mysql 5.5.8, php 5.3.5

when i'v use install.php to auto-configuration system :
after i inputed the necessary information, it replied "Congratulations, Piwigo installation is completed......" no errors displayed on the screen but it accentually it did not work.
after several times of trying, i find that the installation process did nothing in database. There were no tables  created.
Then i checked the sql files and find that the problem is the instructions contain a syntax "TYPE=MyISAM", which mode nolonger worked in new version of mysql to create tables.
so i used an older version of mysql temporarily, installed piwigo, and move dbfiles to overwrite the files in newversion.
at least it works right now,but i don't know if there'll occur further errors

surely it's mysql's compatibility problem.  but i also sure this is a big problem to piwigo, this marvelous project. It will stop new user into piwigo and perhaps will incur further upgrade breakdowns(if need new table),its very serious.
