I have Windows Vista and I think it may be something to do with that, but after I finsihed my download of EB1.0 at 637 MGB, the first thing i noticed was that it had no unique symbol on the installer picture? Is that right? But after I click to install it A small black screen pops up very quickly and then disapers and thats it.....the black screen just shows the location of the file on my desktop...mayeb i download a corrupt version?
