Java Virtual Machine Launcher Error: A JNI error has occurred, please check your installation and try again.

I've downloaded the program, but i can't open it, I just get the error message as mentioned in the title. I have been trying to fix make it work for the past hour, but without luck.
I have downloaded the latest version of BlockMap (2.4.1).
I also installed OpenJDK and tried to open it with that, but when doing so, nothing happens.

Do you have any idea as to why it won't start?

Thank you in advance.

Without any logs I can't do anything. Please try running it from the command line java -jar BlockMap-gui-2.4.1.jar and paste the output here. Also please provide some basic information about the operating system you are using.

You are not providing a correct path to the jar file / You are not in the correct working directory. This is a basic command line usage issue and not specific to BlockMap. (To be honest, your entire issue is very likely a generic Java installation problem and not specific to BlockMap)
