Graal v6 Error

[WaDaFack]

I just reformatted my computer the other day, I installed Graalv6 but for some reason I'm getting this error when I try to open it

"C: \Program Files\Graal\Graalv6.exe
This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

I tried reinstalling it/updating it countless times, it doesn't work!

Anyone might know what the problem is? =o
