Diablo 3 stuck on updating tools

Yesterday I updated the Diablo 3 Launcher, now I got a "Failed to update tools" tooltip that when you dismiss it, it closes the launcher, how do I fix this fault scenario?Here it would seem like many others have the same issue and couldn't fix it even after uninstalling...

Some report that it took few kills before it started to work, but as these issues with Mo P/D3 seem to be based on some black magic, nobody knows..That is, after deleting them before trying it again. Starting over with trying to mark Updaters as well for Combability Mode. The Launcher is now happily updating my files as it normally does on a Patch. tried all 3, still stuck I hate blizzard, ever since they installed their stupid "updating setup files.." on beta and now d3, i can't download anything and it keeps stucking it self at 90%...Seriously, If I can't play because of something so shi*y...
