i've tried to install the latest (4.4) msp430 compiler into ccsv6.... after the download and provisioning operation completes, i'm asked to restart ccs -- which is to be expected....
but then, i see a message for a windows installer that is attempting to install ccsv5!!!!
i did have ccsv5 installed in my system as well, but i removed it.... note that removing ccsv5 is apparently not robust; mine uninstall got stuck "cleaning the registry"....
bottom line -- i have no way to install the latest msp430 compiler....
