Java deploy - removes java???

[meanoldman]

I am trying to deploy Java updates to my users' computers. I am having mixed success though in that if a computer already has the version of Java I am deploying installed, instead of skipping the install, it appear to remove Java altogether. The really odd thing though, is that if I look in the applications event logs, it shows these two results:

Product: Java(TM) 6 Update 29 -- Configuration completed successfully.

Windows Installer reconfigured the product. Product Name: Java(TM) 6 Update 29. Product Version: 6.0.290. Product Language: 1033. Reconfiguration success or error status: 0.

Other software I am deploying or updating, Adobe Reader X for example, does not do this. Has anybody else seen this, and what is the solution?

EDIT

Apparently there is more not working than I thought. I am trying to deploy 3 seperate items - Java update to v6 update 29, GotoMeeting, and Acrobat Reader 10.1.1

Acrobat Reader update seems to work OK.

Java not so much. It shows up in the add/remove programs list and is uninstallable from there, but if I go to Oracles website and try to verify the install it appear to not be installed properly. Or if I try to open the java cpl in the control panel I get an error that the item cannot be found.

GotoMeeting does not appear to update or install at all unless I uninstall whatever version is on the computer first.

Thing is though that I don't see any glaring errors in the Application event log. I get log items like this on for G2M which suggest the item installed correctly

The install of application GoToMeeting 5.1.873 IT Install Manager from policy G2M Update succeeded.
