Running Java gives "Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'"

Question

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\jvm.cfg' 

I tried uninstalling, and got a message saying a DLL was missing (unspecified) Tried re-installing, all to no avail.

At the same time, when trying to start Scala I get:

\Java\jdk1.6.0_25\bin\java.exe was unexpected at this time. 

Checked %JAVA_HOME% and %path% - both OK

Can anyone help?

Answer 1

I checked my environment variables - JAVA_HOME & PATH and they all refer to C:\java. So this was bit frustrating. After sometime I found that the default installation also copied java.exe, javaw.exe and javaws.exe to C:\Windows\System32 (i.e. uninstall of JRE didn't go well). I just removed them and voila, I'm back on track. That annoying error is no longer popping.

This works for me

So, If exists, remove java.exe, javaw.exe and javaws.exe from System32
