not working
What now.I Need to play spiral knights I didn't play them 1 yearh.

The launch screen flashes ever so briefly without actually launching the game. Non-Steam user, been using the same desktop shortcut for over 3 years. Re-downloading the game worked.
i try to play on steam but nothing I start game and game doesen't start but steam says that i already playing the game.I update my video card to lastest version and reinstal Spiral Knights thousand times.It all begins when I install windows 7 and upgraded my ram to 2 g since then spiral knights will not work

If you have the Catalyst Control Center installed for your graphics card please try setting the Catalyst A.I. slider all the way to the left or standard/disabled. The Catalyst A.I. option can be found under the 3D settings menu of the Catalyst Control Center. On old early X series Radeons the Catalyst A.I. can cause unexpected graphics problems in Spiral Knights.
I made everything what you say but nothing. everything remained same.I still can't play spiral knights.

you say it begin when you change to windows 7 right?
maybe your old java is not compatible with your new windows 7, try reinstall java and install new one which compatible for your new operating system. and btw make sure you choose the right version based on your desktop~ x86 (32bit) or x64 bit.
my computer have java 7 what is compatible with windows 7 but the game is not running i click play but spiral knights doesn't appears but may computer says I am playing spiral knights maybe is something with windows 7

hmm maybe try check your Ram? in your pc screen ctrl + alt + del > start task manager > go to performance tab and look at physical memory (MB), in there : total (your ram installed) cached (your ram used by windows and program) available (free memory that currently in load and ready to use) free (used only when pc under extreme condition).
take a note, if your total is not same as Ram memory you currently use now then there is something wrong with it or try reseting your Ram memory (some people have their Ram not installed which make them can't run any game with big memory usage).
there still other possible problem that come to my mind..
- your java is not allowed by firewall or other program (http://wiki.spiralknights.com/Technical_issues_FAQ)
- new java version not working (try install old one)
- your gpu not working with your new windows 7 (especially with old integrated card)
- windows 7 already took over 1gb to run their program and spiral knights in windows 7 can use up to over 1gb too (try disable some program that you currently not use, just in case if your memory too low to run this game.. but you can still play though even with 500mb memory but lag is possible, under 100mb can make your game not running).
My memory is 2024 MB and that is what I currently use.Used memory 36% and free memory 64%.

but may computer says I am playing spiral knights maybe is something with windows 7
Where/how does it say this? If it's the icon on the taskbar, then it could just be that the game window isn't being switched to. If you can, open task manage (ctrl+shift+esc) and click spiral knights on the applications tab. There should be a 'switch to' button.
That is, if it's actually working like that. Could you provide some more information on how your computer says that you're playing spiral knights?
Your computer seems rather low spec... Perhaps it simply can't handle the game properly?
when I click on the game game won't run. I open task manager and I go to the processing there is 'java.exe'-spiral knights.but on running nothing.I now my game works because my RAM and procesor are going crazy. processor goes to 79% workload and my RAM goes 20% additional workload.but spiral knights ware working when i was still having windows xp and. I install Windows 7 and they stopd working
Let me tell u one thing i have
Intel core2duo processor 1.8 Ghz
2 GB ram
Windows 7 Ultimate
No graphic cards ..
and Can still play spiral knight in low settings lol .. u need a good processor i mean upgrade it .. dual core or quad core .. ;D and also Change the mother board , start using Gigabyte boards .. ;D ..
So I recently downloaded windows 10 and it wiped my computer, I now have the latest java but spiral knights wont work, it doesnt open and when it occasionally opens it says some crap about there being multiple sk tabs open, I check task manager and there is only 1 sk tab open...What can I do?
This is my problem for 3 years now, on running process says "java.exe" running and using my memory or sometimes says "javaw.exe", process are running but theres not tab running on desktop.
Are you a steam user and logged into steam while trying to download? (If yes, it redirects to try and have steam dowload)
The solution for this would be to download it via this old link (the microsoft installer).
If no, I'm not sure. Could always just try the direct link supplied above.
