[LWJGL] "Can't load IA 32-bit .dll on a AMD 64-bit platform"

Trying to play LibGDX with LWJGL3 on my Win10 desktop. Worked fine until I downloaded the latest version of LibGDX. Now I get the following error:

Using IntelliJ. The following JARs are imported class librares:

  • gdx.jar
  • gdx-backend-lwjgl3.jar
  • gdx-backend-lwjgl-natives.jar
  • gdx-natives.jar

Don’t really get why it tries to load the 32-bit DLL. Don’t even have a 32-bit JVM installed on my computer.

Strange. I’m on gdx 1.9.6 + lwjgl 3.1.2, and have no problems with intellij on oracle 1.8, 64bit JDK (but on linux, not windows)

Of note, I don’t use gradle or maven, but get the correct files from the maven repo.

I downloaded “latest” from nightlies. What makes LWJGL try to load 32-bit dll?

It seems to work with the gradle project generated by gdx-setup. Just a bit annoying that I have to migrate my project.
