  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
