Board arduino_101 (platform arc32, package Intel) is unknown

Updated my software and now I can not fix this issue with my new boards. What changed to the 5.0 version. Tried two different pc's and no joy. Two different boards and same issue.

What "5.0 version"?

Get this error no matter which revsion before the 1.6.5r. Tried on other pc with windows 7 not 10 and same problem. Never had issues with the other products before how come the IDE for the Arduino 101 Curie does not work period??

Error compiling.

Did you install the 101 board package via the board manager (tools -> Boards -> Board Manager, find 101 entry, install it)?

What did you upgrade? What version of the IDE are you using?

1.6.10 is bad (though most of the problems - I think - only hit AVR boards, a few are general). 1.6.9 and 1.6.5r5 are the good ones right now.

If you've got bad juju left over from installs of other versions, Uninstall, blow away c:/users/(your username)/AppData (hidden folder)/Local/Arduino15, and reinstall to get truly clean install.
