Just found something else that the download must have done - sometime back (maybe when I updated SplashLite?) the volume icon disappeared from the notification area of the taskbar on my computer, and I had to use the more cumbersome volume control option instead but, since I deleted the SplashLite 1.7.1 download, the volume icon has reappeared. I don't know how a download in one folder can affect so many things!
I am using Windows XP.
I got a scary grey window with an image of a net on the right-hand side when Windows opened yesterday, so I did a boot scan with Avast. This gave me 3 error messages about the SplashLite 1.7.1 download, saying that setup files were corrupted. My downloads folder has been taking ages to open properly, and other folders have been quite slow too, including those on external drives. I uninstalled the program and deleted the download, then re-downloaded and reinstalled - slow running again. After deleting the download, everything is running fast again, and SplashLite seems to be working fine. Just thought I'd tell you in case there is a specific problem with your version of SplashLite.
