Folder exists, but empty. MD5 is correct for downloaded files. I have tried x86 and x64 (on a x64 system). Installer does not stars.When you double click mouse cursor changes for a few secconds to the clock and nothing happends.
It just stars and ends. No error messsage is on the screen. I think there is a problem with windows Application Data folder redirection. I was asking for a log because of this. I have downloaded it several times just to check that it is correct. Anyway do you have the correct MD5 for the file?
