java.lang.UnsatisfiedLinkError: Cannot load 64-bit SWT libraries on 32-bit JVM

Last time when I tried to open my Eclipse it came with this exception in it's crash report. I did not change anything on my eclipse not with Java version then why would this happen ?

Then I realised I has updated Firefox with the latest version. And when it needed latest JRE it installed new JRE but it also updated the PATH in the environment. And also smart enough it put new path in front of all other paths.

AND Firefox is not available for 64 bit, although I am running on 64 bit machine, Firefox 32 bit got installed and that also installed 32 bit JRE without asking or checking if my machine is 64 bit ! ( or I guess it detected it but didnt found 32 bit as I have a 64 bit one ! ).

Anyway, I removed that path from the PATH and it worked fine for me.
