Installing Burp -Suite Professional v2020.12.1 in Windows 10

Note : This blog gives a walkthrough to install Burp-suite professional. So, I'm recommending to follow all the steps and the Screenshots given below.

Downloading and configuring Java

We need Java SE 15.0.2 for the installation. This does does not work with version 16 and up.
Go to the above provided link and download the java installer.
It may tell you to create a free account.
Then Just create it and download.

Java SE 15.0.2 - https://www.oracle.com/java/technologies/javase/jdk15-archive-downloads.html

I recommend to download installer directly.
Then install it with default configurations(Do not change anything just press next button)
After installing Java open command prompt.
Then type 'java -version ' and press enter.

As you can see my java version is 16.0.2.

Note : This does not gonna work with burp suite we are gonna install.

So we have 2 options. We can either change the environment variables or we can remove the java version 16.0.2.

In some cases changing environmental variables does not seem to work.
So I'm recommending you to remove this version 16 and then the java version will be the next latest in your computer. (Ex: If we have installed java version 16 and 15 and 14, once we remove java 16 the java version becomes 15. If we remove version 15, java version becomes 14)

Before remove please check what java versions installed in your computer by going to the following path in your file explorer.

C:\Program Files\Java

As you can see in my computer there are 4 java versions. Among them latest version is 16.0.2 then version 15.0.2.

So, let's remove version 16.0.2.
First follow this path

Settings → Apps → Apps and features

After going to this path go down and find for java version 16.0.2

Then you can simply uninstall it by clicking on the uninstall.

Then again go to the command prompt and type;

java -version

Now it should look like this.

Now our java version is 15.0.2
Java installation is completed.

***NOTE - If this method did not work to configure the version of the JAVA. After installing java version 15, remove every other java version. Then it set the version into version 15 automatically***
