I have installed SharePoint Server 2007 Entrprise. And I want to uninstall it. But each time I select to uninstall it, and at the beginning of the uninstall process (i.e. of the progress bar of uninstall process), the uninstall dialog will suddenly be terminated/disappeared (without any error message). From control panel, I can see the "Size" of installed SharePoint Server 2007 Entrprise is not available (seems very weird). I can also execute the SharePoint Central Administration from start menu -- so seems some SharePoint function still there in my machine?
Any ideas what is wrong and any solutions? Here is a screen snapshot of installed programs (with detailed information) of my control panel.
I am using Server 2008 x64 with SharePoint Server 2007 x64. The SharePoint Server 2007 Server x64 is trial edition (trial period expired) and it is why I want to uninstall it.
