Of your first server and besides all the advantages that they give you right here i run my own server with apex hosting and i think something they have that is amazing is that online console that you could access through your phone at any moment meaning that you could control

Have a newer version and it’s not working we need to understand that any minecraft above 1.16.5 will require you to have the newest java out there which is java 18th and any version below minecraft 1.16.5 will require you to have java 8 and that is the reason you’re getting an error

Regarding your java installation while trying to run minecraft another reason could be that you have two java instances on your computer and we’re going to check that to make sure that we only have the right java instance in our computer so before we fix the issue we

Need to find out what’s the origin of this issue go ahead and click on type here to search and type auto remove programs where we’re going to check what java we are running in our computer here in search list go ahead and type java and that is going to let you know what

Java you have as you can see right now i have java 18th meaning that i could run any minecraft up with 1.16.5 with no issues i could run modern minecraft i could run a minecraft server but what happens if i want to run for example on

Our craft server our craft as you might know is based on 1.12.2 meaning that i will need the older version of minecraft to fix our issue pretty much we just need to know what version of java we have and what version of minecraft we’re trying to run for example right now i

Have java 18 but let’s say that i want to run a minecraft server that is based on minecraft 1.12.2 what i would do is get rid of java 18th as you can see i don’t have job i think anymore and i’ll click on that link in the description

That says java 8 because that’s the java that i’m going to need which will bring me over here is our reading guide on how to install java 8 then i’ll click here where it says download java 8 that will redirect me over here and i will just download windows offline 64-bit very

Important that no matter what java you’re installing either java 8 or java 18 you download the 64-bit version because if you download the 32 version that is only going to allow you to give 2 gigabytes to minecraft either minecraft or microserver you will only be allowed to give two gigabytes so

Let’s say that i want to run an older version of minecraft and i need java 8 i’ll come over here to this website i’ll click windows offline 64-bit once you click on that link it’s going to start downloading java 8 immediately i mean in my case it’s going to ask me where i

Want to download it because that’s how i have it set up i’ll just put it there in my downloads folder and once it finishes downloading i’m going to drop it into the desktop let me name it java 8 so you don’t get confused as you can see now i

Have java 8 right this is the java i’ll need to install if i want to run an older version of minecraft if i want to run a newer version of minecraft however i would just click on that link in the description that says java 18 and i’ll

Where i want to download it but for you it’s just going to start the download immediately and then once that java 18 downloads as well i’m going to put it in my desktop so you guys don’t get confused i mean by now it’s pretty straightforward it’s not really hard to

Understand any minecraft above 1.16.5 will require you to have the newer version of java any minecraft below 1.16.5 will require you to have java 8. and if you are wondering for micro 1.16.5 exactly what version do i need you will need java 8 for micro 1.16.5 i

Believe you will need java 8. so now i have both javas and that is pretty much the way to fix it let’s say that i want to run an older version of minecraft i’ll just install java 8 it’s pretty straightforward to install java just double click on it and then you’ll get

The installation menu right here just click install and just let it install for job i think it’s pretty much the same thing you’re gonna get an administrator sign go ahead and allow it and then once you allow it you’re gonna get the installer just click next on the

Installer and install java it’s pretty easy and as you can see java 8 has been installed meaning that i could run any minecraft below 1.16.5 and before we finish this tutorial i have to let you know let’s say that you went into your java installation and you noticed that

You had java 8 but you really need java 18. you got rid of your java 8 then you install java 18 however let’s say that now you’re trying to run a server you’re trying to install forge or optifine and they’re not working properly yet that is

Because you need to run a jar fix in order to run a jar fix just click on the link in the description that says downloaded jar fix which will bring you to our written guide on how to run a jar fix but the main thing here is to click

Download graphics here which will then redirect you over here where we’re going to look for this blue line that says jarfix.exe we’re going to click that line in there and that is going to immediately start the download in my case it just asks me where i want to

Download it i downloaded it to my downloads but i’m going to drop it into my desktop as you can see right there now i’m going to go ahead and close out from the browsers and to run the jar fix after you install java the right version

Of java that you need you’re just going to double click on it and that is going to prompt you with the administrator sign once you allow it as you can see java has been applied meaning that any jar file on my computer is now updated to the java version that i installed

Which in this tutorial will install java 8 but if you install java 18th it will apply job by things to all your jar files so jar fix will help you fix your jar files that is why it’s called jar fix right so let’s recap what we just

Did on this tutorial pretty much i explained to you that any version below 1.16.5 of minecraft will require java 8 and any version above 1.16.5 would require java 18. some people say you could use java 17 and i have used java 17 but i still get errors sometimes so i

Just recommend that you use java 18 because that for sure will help you out a lot more anyways i hope i was able to help you fix your java runtime instance problem whatever and if you enjoyed this tutorial don’t forget to subscribe and as always bye bye
