CPU: intel core i7-6700HQ 2.6 GHz
GPU: Nvidia GeForce GTX 970M (4gb)
SSD 250gb
RAM: 16GB DDR3 1600 MHz
The game launched and ran fine till yesterday but It lagged for some reason when I was on a 4 people team doing the 3 Vanaduke levels and my gpu was using 0,5% so I'd search for some solution and then I proceeded to update java, from then the game stopped launching. I uninstalled all previous java versions and installed the newest 64 bit and after testing the game the 32 bit one as well, but the game doesn't run still. I tried reinstalling it on steam but the install process stops at "launching 99%" and when I quit and press play nothing happens. I tried installing it outside steam and the game runs fine but unfortunately I merged my account with steam and can not play it there anymore 😥. Help :(
Solution I found after searching and testing many things. I saw a video on fixing steam games that don't launch and it suggested moving the game to a faster drive. I moved Spiral Knights to my "E:" external drive and it is able to launch again. My C: drive in which the game was previously is an SSD (propably older than E:), it had ~50gb of free space and ran the game yesterday. I don't know what went wrong... 😅
