I have found two wise installers that will not start on my machine. I own a dell 8300 series and both TaxCut 2004 and ThumbsPlus 7.0 when double clicked start the installer and then it immediately disappears without installing. I can hold down Enter and after about 100 times it will install the software... Any ideas why I am having this problem? I disabled HyperThreading because I thought that may be causing it, but it still does not work.
