Default JDownloader doesn't start.

It's been happening since today, I click on the JDownloader shortcut, and nothing happens, not even the splash screen.
I've tried to uninstall Java and then reinstall it, didn't help.
I tried to click on JDUpdate.exe in the installation folder, nothing happens there too. I just get the standard Windows 'waiting' cursor for 3-4 seconds, then it stops. Nothing happens.

Please help...

You probably already have an instance of jD running. Please, kill the process. It might be called java or javaw.

If jD still doesn't start properly, please provide an Emergency Log.

I do see javaw.exe running, if I end it and run JDownloader, it just appears again and nothing happens.


ATTACHED: jderr.txt and javalog.txt. I couldn't see any file called jdlog.txt.

Log reports that there's another instance of jD already running:
10 1/13/11 7:38:26 PM - INFO [jd.Main(main)] -> existing jD instance found!

In Task Manager, switch ON the checkbox for showing processes of other users.
It may be started as process of SYSTEM user, so you'll not see it normally (Vista and higher).

Maybe your comp is starting jD at the system start? Check autostart or
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
registry key.

Nope, no process related to jD or Java except jusched.exe, which I suppose, is the Java update process.
Tried checking the checkbox.

jD is not set to startup either...

Hmmm... maybe this shortcut is somehow incorrect/damaged?

Did you tried to restart your comp and then run "jdownloader.exe" directly (from the command line or by locating it through "My Computer" and then double click).
Or you may execute (from the command line, when you're in jD home directory): java -Xmx512m -jar jdownloader.jar

If there's another jD instance (started from the same location), you may try if it's possible to force it to the foreground by executing at the command line:
java -Xmx512m -jar jdownloader.jar --focus

The last thing (but before you try it - backup your config folder in the safe place in case of any crash) - you can try to force jD to run new instance by executing:
java -Xmx512m -jar jdownloader.jar --new-instance
.

Done, no effect

I have heard no complaints about Java 32 bit JRE 6 update 21. This version can be downloaded from java.sun.com/products/archive for Windows or Linux users.

I'm using Update 23. Isn't using older versions very dangerous?

JRE 1.6 update 23 has at least one bug concerning the Synthetica styles. As long as you don't use one of those styles, you can continue testing it.

An older version isn't necessarily more dangerous. A new version can be more dangerous because of new bugs.

older version is not dangerous, as java 1.7 is still in development. 1.6 update 23 is latest stable version of java.

please also make sure you remove ALL other java versions from computer before installing another one.
and then create new logfiles please

I think you need to cleanup your Java and re-install JRE 1.6, not 1.7.
When did you install Mercury?
To check your JRE: Control Panel - Java - Java - View.

Default I have similar problem

I hope this post won't confuse the issues cyanide911 and denka have. But my problem seems similar enough to warrant putting it here.

If you like, I will start a separate thread.

I have a start up problem and it seems to be related to Java too.

I'm running Windows 7 Ultimate (x86)
Jdownloader 0.9.581
Java 1.6.0 update 21

The only program change that has happened recently is uninstalling Quicktime for an unrelated issue. After uninstalling, I had to reboot pc. I then ran Jd and it prompted for updates that it installed. Then normally Jd restarts on it's own, but this time it didn't.

Anyway, when I run Jd I get the following error message:

Window Title: Launch4j
Error message: An error occurred while starting the application.
Access is denied.

I tried uninstalling Java, reinstalling. Same problem.
Uninstalled Java, installed Java 1.6.0 update 23. Same problem.
Uninstalled Java, reinstalled Java 1.6.0 update 21. Same problem.
Went to program folder, double click jdownloader.exe. Same problem.
Still in the program folder, double click jdownlaoder.jar. Jdownloader starts up. Looks like normal but won't download any files in my list.

@denka

javalog.txt:
ERROR: JVMPI, an experimental interface, is no longer supported.
Please use the supported interface: the JVM Tool Interface (JVM TI).
Error occurred during initialization of VM
-Xrun library failed to init: jvmhook

=> Maybe search JVMPI and hide it, see the result (post the log).

jderr.txt:
Picked up _JAVA_OPTIONS: -Xrunjvmhook -Xbootclasspath/a:C:\PROGRA~1\HP\QUICKT~1\bin\JAVA_S~1\classes;C:\PROGRA~1\HP\QUICKT~1\bin\JAVA_S~1\classes\jasmine. jar
Error: could not load Mercury Interactive support. Please run the setup again.
If the problem persists please contact Mercury's Customer support.

=> If this is still the same, contact Mercury's Customer support, ask how to cleanup properly.

@FloaTOR
Please post logs that you have.
