Question

Hello guys...

I downloaded JDK 6.0 (btw is it the same as JDK 1.6?)
Anyways, when i want to install it a error message pops up during instalation that says:

Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support or package vendor.

So what can i do? I red somewhere that viruses or adware can be a problem. So i ran all my antivirus programs(Avira, Avast, Spybot, Malwarebytes) and after that, the error messages still appears.

I even turnd off my avast On-Access Scanner but doesn´t help either.

My OS is Windows XP.

Hope someone can help me out on this, i already spent so many hours on this problem.

Thank you...

java

I've never run into this problem, but Microsoft and Java both have pages dealing with it.

Redownloading usually does the trick. Most likely something got corrupted in the download.

What is the service pack of your windows and can you post the link you used for downloading?

The link is correct. I don't know what the problem is.

Have you tried this link:
http://www.java.com/en/

I don't know if it is going to help you, but you can try.

You said that my link's installation was successful. So why try to install another jdk?

Also try to open a command prompt and execute this command:
java -version

I got back this:

java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)

Thanks for the links...
But i´ve been there already and couldn´t get help.
So far this forum is my last change to get it working.

I redownloaded it now 3 times and during installing the error comes up again... always at the same spot by around 95%.

But thanks for this suggestion didn´t thought of it.
But sadly didn´t work :-(

i installed the link you gave me and it was successful... but when im going to install JDK 1.6 it´s still the same problem.

And im confused now... It says during installing something like JDK 6 update. So is it just an update or ist it the full Installer for the java development kit?

HelloMe 0 Junior Poster in Training · Answer 6 · 2010-02-11T17:04:49+00:00

I got the same version like you...

Hmm...

Im not yet an expert... so what i have istalled now is the same i tried to install the whole day?

Because from your link it said something about 10mb size and the one i wanted to install got 76,6 MB.

BTW thanks for your help now i got a little hope back...

Do you have an IDE installed. (JCreator, NetBeans, eclipse) ?
Try compiling and running a small class and see what happens

HelloMe 0 Junior Poster in Training · Answer 9 · 2010-02-11T18:21:37+00:00

Won´t work...

Got the message: " javac" is wrong spelled or was not able to find.

Im about to give up :-(

javaAddict 900 Nearly a Senior Poster Team Colleague Featured Poster · Answer 10 · 2010-02-11T19:40:16+00:00

Well how do you run the command and from what folder? Maybe you are running it from a folder that doesn't see the javac command.
Where have you installed java?

Do you have a similar path like that?
C:\Program Files\Java\jdk1.5.0_17\bin

HelloMe 0 Junior Poster in Training · Answer 11 · 2010-02-11T20:57:04+00:00

I got actually 2 versions now. Yours and i DL a JDK 5 version...

The one you referd me to is in : C:\Program Files\Java\jre6\bin

And the Jdk 5 version is in : C:\Sun\SDK\jdk\bin

I set the path in my cmd to both to try out a small class but both doesn´t work.
Ex.: set path= C:\Sun\SDK\jdk\bin

My class is also saved under the class name as text file and .java

Don´t know any further :-(
