Product Install Code Versioning Question

[The Geek]

Hey guys, I've got several product.xml files, all behaving exactly as they should, however one is now starting to give me a problem and it has stumped me as to why. The onyl conclusion: The planets are aligned against me.

Maybe im just doing something wacky here.

Basically, here is a snipped version of the codes node:

PHP Code:

 <codes>
  <code version="1.0.0 beta 4.0">
   <installcode><![CDATA[
    //snip
                ]]></installcode>
   <uninstallcode></uninstallcode>
  </code>
  <code version="1.0.0 beta 3.7">
   <installcode><![CDATA[
             //snip
            ]]></installcode>
   <uninstallcode />
  </code>
  <code version="1.0.0 beta 3.6">
   <installcode><![CDATA[
    //snip
            ]]></installcode>
  </code>
 </codes> 


Yes, it goes from highest to lowest, however thats becasue that is how vB spit it out. I normally hand write these, however after beating my head against a wall for yonks, I thought if I let vB generate it, it might work - but it doesnt.

What happens is that:
Fresh install - 1.0.0 beta 3.7 doesnt run
Upgrade from 3.7 - Beta 4 step doesnt run.

WTF am I doing wrong?

Lovingly,

Your Geek.
