Hi all i'm a french guy so if my english isn't perfect that's normal.

Well i have installed JAVA and JD but when i clic on Jdownloader.exe nothing happen.

I'm on windows seven 64bits please help me

java works in command line

i can't execute JD via .exe file
java -jar jdupdate.jar worked
i can't even execute the jar file of jdownloader.jar
JD installed under my home directory
java version 1.6.0_26-b03

java -jar jdownloader.jar gives me this error: **External links are only visible to Support Staff****External links are only visible to Support Staff**

i have set the path to include java bin

Thanks for any help.

Bye bye

I would replace that JRE 6 update 26 with JRE 6 update 21 ("**External links are only visible to Support Staff**). Update 26 contain some bugs.

Also try this command to disable direct3d :-

java -Xmx512m -Dsun.java2d.d3d=false -jar JDownloader.jar

Note that many French people write English perfectly. If they speak it then it's often with an heavy accent. There are relatively much less native English speakers who speak French or another language.

An hilarious discussion about this phenomenon can be found at "Can French people speak English?" ("**External links are only visible to Support Staff**).

Your English is nearly as good as mine, so don't mind.

Note that in English clic is written with ck (click) - don't ask me why the English added this redundancy.

1.) you have to be in your jdownloader folder
2.) the log shows errors which are a sign for 1.) broken java installation or 2.) broken jdownloader installation
3.) close jd and start jdupdate.jar IN your jdownloader folder

i suggest to remove java, reboot and install java 1.6 32bit again (64bit is not needed for normal desktop apps and uses more ram than 32bit)

Ok guys thanks for your help i'll try that you advice me to do

Well guys i have uninstall JAVA reboot install JRE 1.6.0.21 32 bit as you told me then reboot again and i try to launch Jdownloader nothing happen

I try to launch JDupdate.jar nothing happen

Thanks for your help but the problem still there another idea ?

Please read our rules and provide a proper bugreport!
To which directory did you install JDownloader? W7 has some problems with programs installed to the standard directory.
Greetz

Well i have tried to change the directory but don't world i have intall it to c:\ i try c:\program files\ and c:\users\cachuéte\my documents\

More info i have Avast and Malwarebyte on my laptop and i have install this JDowloader
"jdownloader_jdownloader_0.9.579_francais_275252"

thanks for help

[Jiaz]

why not install jdownloader from
www.jdownloader.org ?

@danzei

Where did you get that exotic version "jdownloader_jdownloader_0.9.579_francais_2752 52"?

Allow java and javaw in your firewall and virus software. Disable (or un-install) the html/web download scanner in your virus software.

Well i try the web installer but it say
"The installer did not stratup correctly on the last run. This is probably caused by a crrupted java VM. Do you want to download or manually select the JVM?"

i have tried to manually select the JVM i have the good java version but it don't works. The installer don't install JDownloader. I have tried to download the JVM but after the download nothing happen.

oh and i have switch off the web resident protection of avast

Thanks for help

remove all java from computer, reboot and install java 1.6 from java.com
then try the installer

Well i have remove all java, reboot my laptop, installed the last java from Java.com and then try the web installer but the web installer say the same thing "the installer did not....." so i clic on locate select java.exe and ... nothing happen

Do not install jD with the web installer but use the portable (multi-OS .zip file) version of jD.

Please, provide an Emergency Log or execute windows_createlog.bat in the jD program folder and provide an archive with the two generated files.

Have you a link for the multi OS .zip file for JDownloader please ?

It's on the Download page. Click on 'Other' and then click on "Download (MULTIOS ZIP without Installer)".

Well i have dowload and unzip the multi-os.zip in c:\ and execute execute windows_createlog.bat

i have join the two documents in a .rar

"existing jD instance found!"

Kill the already running jD instance (java/javaw) in your Task Manager and try again.

mmhhh i have stoped the task and re-execute windows_createlog.bat

the comand line windows appear and it stay open is that normal ?

Did you get new log files?

This is the new files


Thanks a lot for your help remi and Jiaz

You're having exactly the same problems as Kiraitsu in the French forum. See "Impossible d'ouvrir Jdownloader".

Something is going wrong with your JRE.

Can you please execute "java -version" in a command window?

Yeah i have before the problem when i open comand line and put "java -version" before i have an error message that say something like "an error occured...." but i have resolved this problem yesterday and now when i write java -versio it work and tell me the version of java

Maybe that's a french problem (i'm french)

Can you please show the output of that command?

This is what appear

Microsoft Windows [version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. Tous droits réservés.

C:\Users\cachuéte>cd c:\jdownloader

c:\JDownloader>java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

c:\JDownloader>

Please, reread my post #2.

You mean the comand to disable direct 3D ?

No, the first sentence is more important. Remove update 26 and install update 21.

I'll translate it because it's you.

Update 26 contient trop de bogues. Il faut remplacer cette version de java par la version JRE (1.)6 update 21. Update 21 est une version stable. ("**External links are only visible to Support Staff**)

Ok java 21 is installed

As far as I can see Jiaz only suggested to install a 32 bits 1.6 version. He wasn't specific about the update and he didn't write anything about "the last one".

I suppose this misunderstanding is caused because we all write in a language that's not our native language.

maybe you are right.

well sorry for my error. i have installed the update 21 but it don't work at all

Please provide a new log.

I give you the new logs.

Thanks for help

Your JRE is not installed properly. It's not complete. There are missing class files.

I would remove all java from your machine. Also use JavaRa to be sure all remaining bits are removed.

Then install update 21 (32 bits) again.

Show the result of "java -version" and provide a new log if it still doesn't work.

java -version give :

I hava launch JAVARA reboot the laptop and then install JRE6 update 21and it still don't worlk

It could be a problem with your graphics device driver.

Did you try the command to disable direct3d that I gave in post #2?

I would also try to run jdupdate.jar that you'll find in your jD program folder, because it's possible that your jD installation is corrupt.

Can you also show the full path of your JRE 6 update 21?

well i have try the comand of post 2 nothing happen

The path of java is: C:\Program Files (x86)\Java\jre6\bin

and then Jdupdate.jar when i launch it nothing happen

The last potential cause that I see is the device driver. Check with the manufacturer of your graphics card/chip-set whether you have the latest version of that driver for your OS version.

i have instal the latest version of the graphic card and chipset.

it still don't work

I would forward/escalate this case to Orakel/Sun. They should have the people who can find the cause of your problems with running java on your computer.

Ok well thanks for all i'll wait for an answer to my problem thanks for all your help
