When I double click the shortcut to Arduino or on the executable the splash screen comes up it says "loading configuration" in the lower left corner then stops. It has to be a rights issue since it loads successfully when I log in as an administrator but when I'm logged in as one of our regular users it stops like I described above. This is in a school environment on a domain. I tried giving rights to Domain users on the program folder "C:\Program Files (x86)\Arduino" with no success. There must be a folder somewhere that I can give them rights to so as to make it work for everyone isn't there? any help would be greatly appreciated.
A bunch of people have had IDE 1.6.x problems, including IDE crashes and bizarre compile errors, when they have an old 1.5.x/1.6.x installation. Those problems seem to be caused by out-of-date executables that the new IDE saves outside the IDE installation directory. In such cases it appears that the fix is to delete or rename the old "Arduino15" directory and re-install 1.6.x.
On Mac OS X:
/Users/(username)/Library/Arduino15
On Windows:
C:\Users(username)\AppData\Roaming\Arduino15
On Linux:
/home/(username)/.arduino15 (a.k.a. ~/.arduino15)
Thank you!! Suddenly I couldn't get the IDE to run. Uninstalled and updated, still wouldn't run. I thought my Arduino days were over.
Did as you said and it ran fine.
BTW: I am trying to run a sketch with boards and pin files that were created in 1.0.5. Didn't something change with the architecture of the IDE install? I can't find the paths that the author is referring to. She also mentions a boards.txt fie that I don't see either.
Thanks again, you definitely saved the day. Now on to even greater drama and ambiguity.
