After years of working OK, I\'m suddenly getting this message when trying to start the JVM:
Error: could not open `C:\\Program Files\\Java\\jre6\\lib\\amd64\
Had suddenly the same Problem, from one day to another eclipse said
Failed to load the JNI shared library "C:/JDK/bin/client/jvm.dll"`.
after trying to run java on the console
Error: could not open `C:\WINDOWS\jre\lib\amd64\jvm.cfg'
now i just deleted the whole directory
C:\WINDOWS\jre
and everything worked again... i don't know there this jre came from, i hope it was not a virus
