The pre-install requirements check fails to recognize my Java 1.6 installation.

I downloaded: http://installer.jdownloader.org/JD2...6_or_lower.dmg

Mounted the disc image, dragged "JDownloader Installer.app" to the Desktop and ran it.



As shown in the picture above, I received the message "You need at least a 1.6 Java Virtual Machine to install jDownloader."

I modified JDownloader Installer.app/Contents/Resources/app/i4jparams.conf and replaced all instances of 1.6 with 1.5 and was then able to install. It runs, currently updating (which is currently finalizing.)

We only support offical Java from Apple on such old Mac OS versions.
1.6.0-dp sounds like some beta/unofficial build and I guess that's why the level detection fails.

Thanks for the feedback and little howto how to get it running

Habe das gleiche Problem-Könnte mir jemand die Lösung mal in Deutsch erklären?
Danke
