Question

I’m using Magneto 1.7 with the cache disabled and my module enabled.

View the image directly for a clear view.

And this is after deleting the module’s row from core_resource.

What should happen, is this displaying when I refresh the page.

Running This Upgrade:
Magentotutorial_Weblog_Model_Resource_Mysql4_Setup Exit for now

Instead the script doesn’t load, as if it doesn’t exist.

First of all try renaming your Showdown_setup to showdown_setup (all lower case).
The next thing is that your setup file is called mysql4-install-1.php. This looks strange to me. What is the version you defined in your config.xml? Is it <version>1</version>? Because it must match the number in the install file name.
Also you should define <models> in your config.xml like this:

<global>
   <models>
      <showdown>
         <class>Desbest_Showdown_Model</class>
      </showdown>
   </models>
</global>
