Comment 1 for bug 1504386

Just checked on my Win 7 64 with Java 8 both 32-Bit and 64-Bit.

Did not have any problems.

the message
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8

shows, that you are using some modified runsikulix.cmd, since this is not produced with the standard setup.

So take care, that there are no pointers/references to older Sikuli(X) versions in your environment at the time, the java command inside runsikulix.cmd is processed.
