    Cleaning focuses exclusively, currently, on known registry keys. Files are destroyed when the regular uninstaller runs (JavaRa launch the regular uninstallers). But the use of JavaRa arises when the regular Oracle Java uninstaller (MSI uninstaller) does not work ! So all Java rep and files remain in place.

    In my case :

    In my case :

    C:\Users\Carpe Diem\AppData\LocalLow\Sun\Java\jre1.6.0_24
    C:\Users\Carpe Diem\AppData\LocalLow\Sun\Java\jre1.6.0_26
    C:\Users\Carpe Diem\AppData\LocalLow\Sun\Java\jre1.6.0_31_x64
    C:\Users\Carpe Diem\AppData\LocalLow\Sun\Java\jre1.7.0_07
    C:\Users\Carpe Diem\AppData\LocalLow\Sun\Java\Deployment\cache\6.0 with multiple sub dir
    C:\Program Files\Java\jre6 and sub dir

    A fast way is to search by filenames but it’s a very bad idea.

    I think the only good way, but a slow one (not a problem for stable and clean machines), is to compute the hash (SHA-1 or SHA-256) of all files on the computer (like any integrity controller program). Then look at a hash database in JavaRa and spot the ones to delete (or submit to the user for deleting).

    In the development version (which I don’t think is currently available for download) these directories are already detected. Hash computation is much to computationally-intensive, so we’re using regular expressions over environmental variables to get the correct paths.

    I have a reinstall problem with Java, and have been using JavaRa to try to fix this. Even with v2.1 and the latest definitions, I still found traces of old (some very old) installations. In particular, these three CLSIDs do not seem to be picked up:
    and jrecore was left mentioned in several other places (I was not paying much attention to detail, so have no records of all the junk). I hope this helps.

    Meanwhile, has anybody any idea how this kind of log arises:

    1. Where is the country code? This is NOT the MS locale/country/language settings.

    2. Where are the JRE Metrics hidden? This is after cleaning, and a manual pickover.

    3. How do I get Java 7u13 to install? I have been stuck like this for the best part of a year now.

    Thanks for the heads up about the missed entries. We’ll get those added when possible.

    I’m not familiar with the log you’ve posted. It looks like some sort of internal debug log, where Java appears to be attempting to call Java methods (bits of code) but cannot locate them. I would assume a partially installed JRE would cause this issue.

    My best recommendation would be to try a heuristic powered uninstalled app: Revo Uninstaller would be the most obvious choice.

    Good luck.

    Thanks, but isn’t that the point? It is not installed, and will not install. How can Revo do anything when there is nothing to point at?

    As for the missing entries – please check that they are relevant! I may have missed something important.

    Revo can do a deep scan and remove associated files and keys. If it isn’t able to detect that Java was installed, try creating a few fake registry entries in the tree used for ‘add or remove programs’

    In the past I’ve exported a few Java registry keys from a PC with a working Java install and imported them onto a PC with similar problems to you. Once you give it a whiff; Revo does a pretty decent job.

    OK, I’ll give it a try.
