Hi, I’m relatively new to MakeBlock and to Arduino, so any help is appreciated.
I’ve noticed that when I click “Edit with Arduino IDE” it pops open the Arduino IDE v1.6.5, but the most recent version (see https://www.arduino.cc/en/Main/Software ) is v1.6.7.
How do you teach MakeBlock to use the most recent version. (“Help/Check Software Update” doesn’t seem to do acheive this.)
Many thanks,
SK
For Windows, remove the Arduino Folder within the mBlock programs files:
i.e.: C:\Program Files (x86)\mBlock\Arduino
(place it in your documents folder if you have any files you created that you wish to copy from examples, otherwise you can delete it)
Download and install IDE 1.6.7. If possible, choose the install location as ‘C:\Program Files (x86)\mBlock’.
If not, after install, locate the default Arduino program file location (C:\Program Files (x86)\Arduino) and copy it to the C:\Program Files (x86)\mBlock folder.
The new IDE will now invoke from Makeblock, as well as independently from the installer shortcut.
I have done the install tot the mblock folder but it will not let me use the libraries 
its says invalid librarie found in bla bla document/arduino.
Here is the official Arduino ‘How to’ which may help.
Be sure you are running the latest mBlock 3.2.2 and Arduino 1.6.7
I am running the latest mblock and latest arduino will try to uninstall everything and see what it will do after reinstall.
This post is old, but I ran into the same problem.
My solution might help:
Clic on the Extension menu, clear cache and … voilà!
