    Default JDK SE, JRE and Eclipse not working

    I installed JDK SE 7 on my Windows 8, in order to work with Eclipse, which I installed afterwards.

    However, due to some issues I was having, I un-installed both programs. Now, I re-installed both programs, but everytime I try to open Eclipse, I get the following message:

    Error: could not open `C:\Program Files (x86)\Java\jre6\lib\amd64\jvm.cfg'

    I open the Java folder and under I can't find the amd64 folder in the jre6 subfolder.

    Can anyone help me fix this problem?

    Some thoughts: Check the Build/Build Path setup in Eclipse. Something is expecting JRE 6 to be installed at the specified path, and it's likely not there anymore since you uninstalled and reinstalled things. Unfortunately, uninstalling sometimes leaves remnants in your environment variables or in the registry that are used for initial settings the next time you install that same program. Check the CLASSPATH environment variable. Maybe it needs to be updated to the new Java location. Did you reinstall just the JRE (standard Java) or the Java SDK as needed for Eclipse and development work?

    At first, I was re-installing the Java SDK, but then I had the idea of re-installing the version of Java on my computer, which was Java 7.

    Thank you for the assistance though.

    It's always nice to learn something from these annoying events that mostly waste our time, and I'm not sure what you learned from this so that it won't happen again. Perhaps installation order matters . . . don't know.

    Glad you figured it out.
