Hi! I've downloaded PlantUML. However, when I open it I get this:

However, this is not where my JRE is in my computer. The file path for my JRE is C:\Program Files\Java\jdk1.8.0_202\jre. As for the javaw.exe, it's at C:\Program Files\Java\jdk1.8.0_202\jre\bin.
I think this is the same issue that results in the command "java -jar plantuml.jar filename" outputting "Error: Unable to access jarfile plantuml.jar"
