Error invoking method, Failed to launch JVM

[Golden Erection]

These are the errors when I'm trying to launch the game... Can you help please?

Hey Deccal,

Can I ask for some details on your machine?
What Operating System are you on, what graphics card, and the like?
It sounds like you aren't even getting to game code, so something fishy is going on...

The time I've heard of this in the past, someone's virus checker was mistakenly flagging a file, removing it, and causing the startup to fail.
Can you check whether that might be the case?

Thanks!
Danny

I also have same problem. I am not using virus program other than windows defender and there seems to be no problem regarding the game.

I am using Windows 10 Creators Update 64bit
Nvidia GTX 1050 Ti
Intel i5-6500 3.20GHz
16 GB RAM

I also updated my Java after having this problem but still no go.

I've got an amd r5-330m graphics card and using win10, 16gb ram. And I don't have any anti-virus software other then the windows defender that's all.

Would it be okay to ask you to ping me on Skype, and we can perhaps work through whatever issue you might be having? Seems like something new.

I'm also getting the same issue.

Using Windows 10 - 64 Bit
16 GB Ram
Intel i7-7700HQ CPU
NVIDIA GeForce GTX 1050 Ti and Intel HD Graphics 630 (built in).

I've updated Java, which was a pain in it's own regards cause Windows 10 doesn't like to work well with others.

Hey all,

For anyone who encounters this in the future, FYI: No need to update Java, as the game uses a bundled in JVM. So, your computer's installation is unlikely to matter.

If anyone does want to hit me up on Skype, though, I'd love to solve this with someone in realtime.
Getting some meaningful debug output would help a lot.

Thanks!

Hi all,

Thanks very much to DapperPrinny, I have a workaround on this, albeit not a fix.
I'm currently reaching out to Valve for more information on this to pursue and easier solution.

For now, this seems to work:
1) Navigate to C:\Program Files (x86)\Steam\steamapps\common\Metronomicon\Metronomicon
2) Create a file called steam_appid.txt
3) Open that file, and paste, on the first line, just this: 416790
4) Save and close.
5) In that folder, there is an EXE. Double-click to run the game.

This should give you the exact same game/content as running it from steam would. I'm not sure yet why launching it directly From steam is failing (especially on just a small minority of machines), but I'm escalating that to Valve now.
A bit of a pain, but the game is fully functional, hooray!

Thanks all,
Danny

İ ve the same issue, workaround fix is not working.

[Noname1122]

Burn,

Hm, possibly you're having some other additional issue?
If you wouldn't mind reaching out to me on Skype (Daniel.Garfield1), I'd love to debug with you in real time, if you're up for it.

Thanks!
Danny

The same error to me, i created the txt archive with this ID and didn't work, i transform into a .dll and didn't work too.

My computer configuration:

OS: Windows 10 32 bits
ram: 3GB DDR3
CPU: Intel core 2 Duo 3.1Ghz
Video card: dedicated

I update the java version to 8, i newbie (maybe junior) in java development, would be the version? if a do i downgrade to 6.x or 7.x the game works? or is a error on calling the method?

Thanks for cooperation, i love this game!

[Noname1122]

Hey Bosten,

The java version that the game uses is bundled in, so your local installation shouldn't matter. Though, as a common thread, I'm starting to suspect it might..?

I'm going to do some investigation, but if you wouldn't mind helping, you can reach me on Skype at Daniel.Garfield1. I'd love to run some tests with you.

Thanks,
Danny

Update: After further research, it looks like this MAY have been introduced in Java 8, in the packaging code (which is something I cannot fix). However, the fix appears to be rolled out in Java 8, which is not easily compatible to this project.

A workaround which I BELIEVE will work appears to be:
1) Open a command prompt.
2) CD into C:\Program Files (x86)\Steam\steamapps\common\Metronomicon\Metronomicon\app
3) Create a file called steam_appid.txt
4) Open that file, and paste, on the first line, just this: 416790
5) Save and close.
6) Type: java -jar Metronomicon.jar to launch the game.

Note that I haven't tried this, as the issue only happens on a smallish number of machines. But, based on what I'm reading, I believe that this MIGHT work.
Further note: This does require that Java be installed in advance.
