When i try to start cura ( tried it with version 14.01 till 13.10) i get the splash screen and after that it closes. only working version is 12.10...

the error in the output file is:

    Open a CMD window and type "set appdata" and see where your appdata actuall is. Is there something strange about it? I'm going to guess there are non english characters or it points to a network drive or something. Here is mine:


    C:\Windows\system32>set appdata

    Instead of where mine has "Otis" maybe yours has something like: François? Some non english character? That will mess up python sometimes (cura was written in python).

    If this is the problem a quick fix might be to create a second username with no accents, log into windows with that username and see if the problem with Cura is gone.

    When typing this command i got the error about the variabele not being defined. This is what i did (and it worked)

    Start > Right click on this pc > property's > Advanced systemsettings > Environment variables > New

    (im dutch so menu buttons may be different)

    Then i added a variable with the name APPDATA and the value C:\Users\(My name)\AppData\Roaming

    After that cura worked flawless

    I've also patched up the code so this should no longer happen. However, APPDATA should normally be defined, so it's odd that it was no longer set.
