Could not create the Java Virtual Machine

[Thyateira]

My game wasn't launching. So I have run the bat file. It says:
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Any help appreciated. Thanks in advance !

Can you share the whole error log? Either a screenshot or copy all the text that is shown there?

You may see the text below.

Can you try verifying your game files:
Steam Library > Right click Project Zomboid > Properties > Local Files > Verify Local Files
If that doesnt help, can you try launching with the 32.bat file?

[Thyateira]

Hi again,
Unfortunately did not work out..

[Beard]

What kind of error shows up with the 32.bat?

As same as the previous one

[Beard]

In that case can you share the "hs_err_pid" file found in D:\SteamLibrary\steamapps\common\ProjectZomboid?
You can upload it to pastebin.com for example. And can you tell us your system specifications?

[Sud0]

Same issue here.

[Thyateira]

Unfortunately I couldn't find the file you required. Here is my specifications:

CPU: AMD Ryzen 7 3750H 2.3Ghz
RAM: 16 GB
OS: Windows 10 Home Single Language
Graphic Card: GTX 1650 4GB

[Beard]

Those specifications should be more than fine. The log unfortunately doesnt tell us much as to why the game doesnt launch or why Java cannot be created.
Can you try editing the ProjectZomboid64.bat file with a text editor?
Change the line -XX:+UseZGC to -XX:+UseG1GC
Then save and try launching the game through that file to see if that helps.

[Scott Mac]

Same issues. Scoured the forums and previous 'did not launch' threads. Tried running the .bat files and got the fatal exception error as above.
Have previously had it installed and running (ages ago - thought I'd try again when I saw the latest update announcement!)
Have just done a java update tonight. Updated graphics drivers not long ago and they are still current.

console.txt pastebin is here: https://pastebin.com/27qKyZp3

Trying a full reinstall next.

[Beard]

If the reinstall doesn't work, try going to Steam\steamapps\common\ProjectZomboid
There, delete the "jre" and "jre64" folders, after that verify your game files and start the game again.
Steam Library > Right click Project Zomboid > Properties > Local Files > Verify Local Files

This would make sure that it reinstalls the built in Java, sometimes a Steam reinstall doesnt uninstall some leftover files which can cause issues.

Thanks for your effort. It worked for me

deleting the jre and jre64 folders worked. It must not be properly updating the JRE install.
