The Steam version of Spiral Knights refuses to launch, giving the error "Could not create the Java virtual machine". (Other Java based games run properly- and the non-steam version of Spiral Knights runs without error as well.)
I've tried reinstalling both Java and the game to no avail. Any insight would be appreciated- thanks!
The Steam version of SK uses its own Java installation (stored in java_vm directory) while other games / regular SK will use your system Java version. You should copy the files from your installed Java and replace your java_vm folder with it
