Magento Setup Resources : Installer script not running

Question

I am working on a Magento ver. 1.11.2.0 (enterprise).

I am following Allan Storm's Post here.

My modules config.xml :

<?xml version="1.0"?>
<config>
<modules>
    <Invent_Instance>
        <version>0.1</version>
    </Invent_Instance>
</modules>
<global>
    <models>
        <instance>
            <class>Invent_Instance_Model</class>
            <resourceModel>instance_mysql4</resourceModel>
        </instance>
        <instance_mysql4>
            <class>Invent_Instance_Model_Mysql4</class>
            <entities>
                <instance>
                    <table>instance</table>
                </instance>
            </entities>
        </instance_mysql4>
    </models>
    <resources>
        <instance_setup>
            <setup>
                <module>Invent_Instance</module>
                <class>Invent_Instance_Model_Resource_Mysql4_Setup</class>
            </setup>
            <connection>
                <use>core_setup</use>
            </connection>
        </instance_setup>
        <instance_write>
            <connection>
                <use>core_write</use>
            </connection>
        </instance_write>
        <instance_read>
            <connection>
                <use>core_read</use>
            </connection>
        </instance_read>
    </resources>

...

The class Invent_Instance_Model_Resource_Mysql4_Setup seems to be called ok as before i created it, it gave out an error saying it doesnt exist.

My files structure looks like :

Module file structure

with the contents of my installer being

echo 'Running This Upgrade: '.get_class($this)."\n <br /> \n";
die("Exit for now");

after removing all cache, i reload my admin module and it loads without giving output or obviously without running this script.

Can someone please show my what im doing wrong? I have double check the module version number (0.1) and cant figure out why its not running.

Is there anything wrong with my modules model setup? thanks for any assistance here!

Looking at the above everything there seems fine.

It is worth checking the core_resource table and look for instance_setup in the "code" column if the value in the "value" column matches the version number in the config.xml then the script won't be run.

You can always delete this row to run the install script again.

this has happened to me several times. Sometimes it is the most obvious answer!
