Getting an error when using the installation routine at creating DB. When doing it manually via phpMyAdmin I get the following ;

Error

SQL query:

CREATE TABLE isys_const_system (
isys_const_system__id int( 10 ) unsigned NOT NULL AUTO_INCREMENT ,
isys_const_system__isys_const_system_type__id int( 10 ) unsigned default NULL ,
isys_const_system__const varchar( 255 ) COLLATE latin1_german1_ci NOT NULL default '',
isys_const_system__value int( 10 ) unsigned default '1',
isys_const_system__description text COLLATE latin1_german1_ci,
isys_const_system__store_id int( 10 ) unsigned NOT NULL default '0',
isys_const_system__doku_cross_reference text COLLATE latin1_german1_ci,
PRIMARY KEY ( isys_const_system__id ) ,
KEY isys_const_system_FKIndex1 ( isys_const_system__isys_const_system_type__id ) ,
CONSTRAINT isys_const_system_ibfk_1 FOREIGN KEY ( isys_const_system__isys_const_system_type__id ) REFERENCES isys_const_system_type ( isys_const_system_type__id ) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE = InnoDB DEFAULT CHARSET = latin1 COLLATE = latin1_german1_ci;

MySQL said: Documentation
#1005 - Can't create table '.\i-doit\isys_const_system.frm' (errno: 150)

Also get the same error mesaage when trying to load the mandator DB also.
I'm using MySQL 5.022, php 5.14 & Apache 2.054 on Windows XP.
