I used to run eclipse on my laptop. I have installed and used Secunia PSI application in order to update the apps, but once I done that I cannot run Eclipse.
This is what I have:

I set the PATH to the directory which contains javaw.exe app. The path at the PATH variable is the same as of CLASSPATH variable. So, what are your resolutions? Done, it works now. I just simply needed to add '.;' at the end of the path link at the PATH. Cheers
