Hi!
I have used FileBot for a long time with no problem.
Now all of a sudden I can't start it anymore.
I have tried to platform exe without success.
Is there any logging somewhere I can turn on?
Thanks!

1. Open CMD
2. Run /path/to/filebot.exe from CMD and see if there's any output

There must be something horribly wrong with your Java setup. Check if your environment variables make sense. Also, make sure you're running the latest Java 8.

Variables
JAVA_HOME -> C:\Program Files\Java\jdk1.8.0_92
_JAVA_OPTIONS -> -Djava.net.preferIPv4Stack=true
The JAVA_HOME path is correct.
All other java applications are working fine.
I have uninstalled and installed again FileBot several times without any success...

This doesn't mean anything. Ignore.
Code: Select all
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
This is severe. This is why it doesn't work.
Code: Select all

If you google for that message you'll find lots of results.
According to the first result,
rt.jar (contains all Java core classes) is not in the
CLASSPATH. Either a faulty install, or a bad CLASSPATH environment variable.
Reinstalling FileBot will not fix your Java issues. Reinstalling Java might. This might be a
launch4j issue that you could report with the launch4j people, but most likely it's just something odd about your setup that causes things to hiccup.
EDIT:
launch4j uses the registry, so the issue might be there.

Hello,
I had this problem for three days, my firefox requested a JAVA update because it was outdated, I had 8 update 77 and it updated to 8 update 91 for the 64bit version and it hosed my system until I updated/installed the 32bit JAVA.
my FileBot GUI wouldn't even come up, and whenever I used the context menu commands the dos window would flash but nothing would happen.
you need to install/update both versions of JAVA if you have a 64bit system. I don't know why JAVA doesn't say that, they only mention that if you use both versions of a web browser that it needs to be done.
Hope this helps,
Shaggy
