Don´t work on drupal 6.15 and 6.16

I Chek the md5sum and it´s correct.
I try to install the module in two machines and I have the same warning in both of them:

* user warning: Incorrect table definition; there can be only one auto column and it must be defined as a key query: CREATE TABLE weather_es_data ( `did` SMALLINT NOT NULL auto_increment, `cod_pro` INT unsigned NOT NULL DEFAULT 0, `cod_loc` INT unsigned NOT NULL DEFAULT 0, `day` VARCHAR(15) DEFAULT '', `ampm` VARCHAR(2) DEFAULT '', `sky_txt1` VARCHAR(50) DEFAULT '', `sky_txt2` VARCHAR(50) DEFAULT '', `sky_img1` VARCHAR(25) DEFAULT 'nodata', `sky_img2` VARCHAR(25) DEFAULT 'nodata', `rain` INT unsigned DEFAULT 999, `snow` INT unsigned DEFAULT 9999, `tmax` INT DEFAULT 99, `tmin` INT DEFAULT 99, `win_dir1` VARCHAR(50) DEFAULT '', `win_dir2` VARCHAR(50) DEFAULT '', `win_spd1` INT unsigned DEFAULT 999, `win_spd2` INT unsigned DEFAULT 999, `iv_max` INT unsigned DEFAULT 99, `rsk` VARCHAR(50) DEFAULT '', PRIMARY KEY (cod_pro, cod_loc, did) ) /*!40100 DEFAULT CHARACTER SET UTF8 */ in C:\wamp\www\drupal-6.15\includes\database.inc on line 529.

The machines are:
- windows XP with wamp, drupal 6.15
- windows with IIS and mysql, drupal 6.16

In both the problem is to create the table weather_es_data, the other tables: weather_es_aemet and weather_es_config was created sucesfull.
