Problem instaling XML Starter Kit 4.1.4

Hi, I downloaded the XML Starter Kit 4.1.4 but when I try to install I get the following message: ---------- Warning: Some files are marked to be renamed or deleted at the next restart of your computer. Since deleting files after restarting can influence this installation, Setup will stop now! Please start Tamino 4.1.4.1 Setup again after you have restarted your computer. ---------- I have restarted several times… I’m using Windows 2000. Any ideas? Thank you, JN

Found the problem: spyware in the computer…
