yes downloaded from kodi site and yes it it installs then message appears when opening,my machine is a lenovo E545 thinkpad,i have win 7 home premiumStupid question first, are you sure you downloaded the correct version for your machine?
Secondly, is this error occurring when when you are installing, or it allows you to install, then when you try opening it, you get the error?
Where did you get the download from?
What sort of machine are you trying to use?
