RapidMiner Java could not be launched - Error 1

Question

I have installed RapidMiner and when i am trying to launch the application, i get

Java could not be launched Error 1

After researching, i have found that running the .bat file could give a more detailed error message which is:

SEVERE: Failed to read RM preferences for user specified license settings (As shown in the picture)

System Language is Greek (i am not sure if this is the problem with the path)

Any suggestions?

Java Version 21.XX.

Citing the solution from the RapidMiner Community post https://community.rapidminer.com/discussion/comment/73142/#Comment_73142

There is a known issue with non-ascii usernames in 10.2 / 10.3.

As a workaround you could point your .RapidMiner folder to another directory by adding i.e. -Drapidminer.user-home=C:\.RapidMiner to line 158 of the C:\Program Files\RapidMiner\RapidMiner Studio\RapidMiner Studio.bat

"%JAVA%" %JVM_OPTIONS% -cp "%RAPIDMINER_HOME%"\lib\* com.rapidminer.launcher.GUILauncher %CMD_LINE_ARGS% would change to: "%JAVA%" %JVM_OPTIONS% -Drapidminer.user-home=C:\.RapidMiner -cp "%RAPIDMINER_HOME%"\lib\* com.rapidminer.launcher.GUILauncher %CMD_LINE_ARGS%

Afterwards you would need to start RapidMiner Studio via the .bat file until this is fixed.
