in trying to download and install the:
Set up and configure your Office desktop apps
i installed it ok onto two differant windows 7 64bit os laptops at differant times, started the download (which has a good 7mb-14mb connection) and install, and got to 87% and froze for hours. i cancelled it and now onwards all i get when i try again is a blank screen for the "microsoft office 365 desktop setup" window.... and nothing happens. ever.
the only answers i can find online are to clear your temp files cache (done!) or to reinstall your os..... which is not an option with the amount of software & data on this machine.
