FWIW,
OP is obviously using an old OS, as in XP, and would be advised by most people, to update that, for starters. Personally, XP was the best OS MS ever made, up until Windows 7.
XP never came with that crap .NET stuff installed and I also NEVER allowed that bloatware junk on any of my XP machines either. Total crap bloat and not needed for much of anything, if anything.
Windows 7 on the other hand, comes with it preinstalled, and in fact can not be removed (stupid as heck)
I'd be totally PO'd also if I were still running XP and TT had to install all that junk PLUS update the map, and NOT inform me. That must've taken about 6 days to complete!! Just the updates to .NET probably took another 5 days!!
Don't blame OP at all for venting that frustration!!
Just got my first TT a few days ago and was instantly PO'd myself when I discovered this stupid thing doesn't even know which version of the Home it needs and there are absolutely NO instructions that are worth a crap explaing anything.
I have a new model that requires the older TTHome and not the MyHome software. Thanks for telling me TT!! Thusly, very first update, which took WAY to long, totally screwed my map up and said map is not usable with this device. Spent another 5.5 hours deleting EVERYTHING off TT and then reinstalling everything with the correct tool.
Will go back to Garmin, when and if I ever buy another GPS, for sure!!
