Downloaded it from itch.io version 0.50.2.
Unzipped the package and double-clicked mewnbase.exe. Nothing happened. No error message. Nada.

Help?

I have the same problem.
Some specs:

Win 10 64 bits
installed on an SSD
The game seems to be written in Java (not sure though) and i'm not sure i have ever installed Java on my PC. Maybe you have to have Java installed?

Well, installing Java did *not* seem to help

Trying to launch the .jar via java -jar desktop-1.0.jar results in:

,,,\AppData\Roaming\itch\apps\mewnbase\game>java -jar desktop-1.0.jar
MewnBase launch args:
[MewnBase] MoonBase.coreFolder = data/
com.badlogic.gdx.utils.GdxRuntimeException: Can't find the data folder here:data/
at com.cairn4.moonbase.MoonBase.create(MoonBase.java:101)

Exception in thread "main" java.lang.NullPointerException

so I copied the data folder intpp the game folder and tried again, still cant launch via the .exe but it does open by launching the jar directly

*edit: of course, I could have avoided copying the data driectoroy if I'd run java -r game/desktop-1.0.jar from the apps/mewndata folder instead of running it from inside game/

*edit 2: See below, he clarified this rambling nonsense ;)

+1, just wanted to repeat that you can run the Java command from the game root, to avoid copying the .\data\ folder. (I missed that point when I first read this.)

C:\Users\whatever\AppData\Roaming\itch\apps\mewnbase> java -jar .\game\desktop-1.0.jar

It seemed like a wild goose chanse considering the game does launch from the jar, but I tried updating my drivers just in case... no dice

Same issue here. Java updated, no run. D=

Windows 10x64

I just realised that I didn't install Java on on my system! Went to www.java.com and installed the latest JRE. It works now!

I feel so dumb... sorry for the confusion.

It's been so long since I've used Java...

I'm having the same issue, Java is updated but I still can't get the game to run :/

So, I got over my annoyance at the launcher not working and played the game enough to realize it's pretty great. Enough so that I bought it again on steam. The steam installer installed some version or other of the visual c runtime and now both that and the itch version work... I'm not sure what version of the runtime it was, but take it for what its worth. This game is super fun :)

Same problem. I just installed java and the game still doesn't run on my windows 10 64 bits :/

It looks like it needs the Microsoft Visual C++ 2010 Redistributable Package (x64) https://www.microsoft.com/en-us/download/details.aspx?id=14632 (I think dude updated the FAQ to include that tid bit)
