    Hi,

    Can you please start the RapidMiner-Studio.bat next to the .exe instead? The exe unfortunately is very bad at giving useful errors :(

    Regards,
    Marco

    Hi Nick,

    What does "hostname" return for you in the command line?
    (Press ⊞ Start, type cmd, press ⏎ Return)

    Either change the hostname to be RFC 952 compliant, or use this workaround:

    Save the following lines in a plain text file with the ending .bat and execute it
    set rmHome=%HOME%\.RapidMiner
IF not exist %rmHome% (mkdir %rmHome%)
echo rapidminer.proxy.mode=Direct (no proxy)>> %rmHome%\rapidminer-studio-settings.cfg
    or manually add the line 
    rapidminer.proxy.mode=Direct (no proxy)
    to the end of your %HOME%\.RapidMiner\rapidminer-studio-settings.cfg file.

    This will disable proxy usage, if you need to use a proxy you can change this setting afterwards in Settings → Preferences → Proxy

    Greetings,
    Jonas

    I have the same problem, but this is very complex for me.
    Is there any easier dummy description for that?

    Hi @FriendOfFoj,

    Assuming you use Windows:

    if you right click on the "RapidMiner Studio" shortcut on your Desktop you should have an option like "Open path".
    Alternatively you could navigate to "C:\Program Files\RapidMiner\RapidMiner Studio" in your file browser.

    This should bring up the installation directory, where a RapidMiner-Studio.bat file is next to the RapidMiner Studio.exe



    Greetings,
    Jonas
