New Post: Java u51 detect issue: Not installed where should be Not applicable or Installed

Hi guys,

I have a problem deploying Java update 51 x86.
I tried to follow this guide https://wsuspackagepublisher.codeplex.com/discussions/462519 updating the MSI code into the rules.
I tried in my test environment and the result are so strange:

• on windows 7 where is already installed the u51, WPP say that is "Not Installed" where should be "Installed";
• on windows Vista where Java is not installed, WPP say that is "Not Installed" where should be "Not Applicable";
  

I think that the error is in isInstallable rule but I didn't find what is wrong.
My goal is to install Javax86 also on x64 machine so I didn't add the Architecture rule.

I classified the package type to Update and the update classification to CriticalUpdates.

isAlreadyInstalled rule:
<msiar:MsiProductInstalled ProductCode="{26a24ae4-039d-4ca4-87b4-2f83217051ff}"/>

isInstallable rule:
<lar:Not>
<msiar:MsiProductInstalled ProductCode="{26a24ae4-039d-4ca4-87b4-2f83217051ff}"/>
</lar:Not>

Other updates work fine (flash and reader).
What I missed?
