Hello Presende,

The problem seems to arise from using colons instead of semicolons on Windows. Replace all colons that delimit individual jar files in your command by semicolons and the graphs should run successfully. Of course, “C:\” must remain the same, with colon.

Best regards

Tomas Waller

PS: Colons should be used on Linux, semicolons on Windows.
