I have installed this just to check the installation procedure, no problems here on win7/64, the code was the same as L. Spark’s. For some reason, things tend to go wrong here for many people, having troubles with instructions, and that makes this site look a kind of suspicious. Dear Ashraf, my Computer says you are a Norton Virus Gen., trying to steal my Facebook credentials. Should I use Safe Mode? Since instructions are always OK, there is, I suppose, no simple solution to avoid such problems.
