I uninstalled version 5.2 and installed version 5.4 but I got message saying "a required API is not available on this installation of Windows". There is a link for more information but when I click on it I get a message saying "the requested URL was not found on this server". I did originally posted this problem in the SpywareBlaster 5.4 Released thread and did receive one reply but thought it may be better if I opened my own thread so it would get noticed more. I am still using Windows XP Home Edition SP3 and also use Google Chrome browser. Does anyone have any suggestions?
