Java could not be launched.

Hi,

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

See attached, I hope this wil help. 

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

I can't find the rapidminder-studio-settings.cfg file

It's works, the .cfg file is created with the script

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

can you please help with the .bat file step? i don't know what you mean? is it file in my laptop or only when the error pop up?

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
