I just re-installed my os (winxp) and I can't install TomTom Home, it dl's the .exe file, but when I try to run it, nothing happens. I downloaded other programs with .exe files and they execute, but this does nothing. I used the one on my device (TT1v3) and the download from the site with the same result. I don't have anything crazy on my pc-firefox, avast. I even shutoff my firwall and virus protection to see if that would make a difference. Any ideas?
