FastQC isn't openning on windows

[M7MD-ElHELALY]

When I double click on the run_fastqc.bat it opens a cmd window for a brief then automatically close after writing this code

java -Xmx250m -classpath .;./sam-1.103.jar;./jbzip2-0.9.jar uk.ac.babraham.FastQC.FastQCApplication

So I took the code in other cmd window and it gives me this error

Error: Could not find or load main class uk.ac.babraham.FastQC.FastQCApplication

At first it showed me this error before downloading sam-1.103.jar file

Error: Could not find or load main class uk.ac.babraham.FastQC.FastQCApplication
Caused by: java.lang.ClassNotFoundException: uk.ac.babraham.FastQC.FastQCApplication

So what should I do. Noting my JAVA version is
java version "1.8.0_421"
Java(TM) SE Runtime Environment (build 1.8.0_421-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.421-b09, mixed mode)

So this sounds like the installation is wrong. Either you're missing big chunks of files, or you've donwloaded the wrong zip file.

The zip file you need is this one. You can't use anything you download off github as that only has the source code and not the compiled classes.

When you've downloaded the file you need to unzip it to a real folder. Windows has a facility where it makes a zip file look a bit like a folder, something like this:

That will not work. You need to unzip it so it's a real folder not a zip file:

Once you have that then you can try double clicking on the bat file and hopefully it will then work.
