Why won't JavaFX programs run?

I'm running Ubuntu 10.04 and firefox. If I go to http://javafx.com/samples/ and try to launch one of the samples I get redirected to a page that says I need a newer version of java.
If I run java -version from the command line I get:
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Server VM (build 16.3-b01, mixed mode)
This is the same version as the one the web page wants me to download. Why won't these demos launch?
thanks,
William

Generally, there are some additional steps to configure the sun java plugin for firefox browsers on Unix systems
http://java.com/en/download/help/linux_install.xml. Scroll down to the firefox section to get a sense of how to do it.
A quick and fast solution (without configuration) to see the demos is to click on the launch button above each demo sample and then open it with javaws (from the bin directory of your java installation). Hope this helps!

Why won't my program run when I schedule it.

I am trying to schedule an executable and it says it is successful, but the program never runs. I even tried setting up a simple batch file that will call the program and when I schedule it it says successful but never runs. When I run it on the desktop of the server it runs fine and the batch job runs fine. I have tried configuring it several different ways and adding supporting files. I have never scheduled a program in this application, so I'm sure I'm just missing something. Can someone please tell me how to set this up or give me an example. It is driving me crazy.

Thanks in advance.

What is "input" and "output" and have you included these classes in your classpath?

Why won't Elements 5 run?

Why won't Elements 5 run on my Win 7 Pro machine? When this custom machine was first set up, all the programs running on my prior Dell Win XP machine were installed on this machine, including Elements 5.
Recently, my hard drive crashed and the mfg couldn't install most of the programs I had, including Elements 5. I still had the original disk and installed the program. It went through the installation and put a shortcut on my desktop. Unfortunately, when I clicked on the short cut, nothing happened. I went to the location of the the executable file and clicked on it. Same thing.
I went to my tech support company and they helped me uninstall the program and we "repaired" the program but it still wouldn't run. We reinstalled from the CD and it still wouldn't run.
Is there anyway, I can get my program to run? If it comes down to having to purchase a new program, I'll just use the Windows photo program. I think whatever is going on is lousy!

Did you try right clicking and run as administrator?
You could also try setting up a new user account an see if it will run from there.

Why won't Photoshop CC run on my laptop I just installed it today

Why won't Photoshop CC run on my laptop I just installed it today. I signed out on my desktop but the laptop still will not run Photoshop CC. It starts but then closes itself down immediately after starting.

Well it is the same Win7 that is running on my desktop and yes I have an internet connection and at that time is was hard wired not wireless. I just downloaded and installed the Photoshop and Bridge Apps. The laptop is about 2 yrs old and it is a high end machine and Photoshop6 runs on it just fine. I sure wish someone from Adobe would answer this question as it is beyond frustrating to me that this stuff works so poorly and you can never get a good answer out of them about anything ever.

Please why doesn't some programs run on the osx mavericks the way it ran on the osx mountain lion, for example , the wizard 101 installer keeps freezing on maverick. Help me !!!

Some apps require updating when a new operating system comes out. Check with the developers of the apps you're having problems with and see if they have an update or workaround.

Nothing is wrong. what your're seeing is by design.

Why won't my eMac run OS X?

I bought an older eMac from someone and tried to install OS X (it had OS 9) but the installer quit and said "the installer has unexpectedly quit (error 1)" . what does error 1 mean? I thought it didn't have enough RAM so I ordered 1GB, installed it, but OS X still won't install. And now when I turn on the computer it tries to run OS X but freezes and a little bow with some text comes up in the upper left corner of the monitor.
Does anyone know what the problem is or what hardware I might update to fix the problem? Here are the specs:
iMac version 1.2.1
CPU: PowerPC,G4 @ 800 MHz
Cache: 256 K L2 @ 800 MHz
1 GB of RAM
32 MB VRAM

The same version of Apple Hardware Test was used for some eMac and iMac versions. It's been a while since I ran AHT, so I don't remember if it says eMac or iMac, but you're certainly describing an eMac.
What color is the label on the OS X Install disc you were given when you bought the eMac? If it's a retail (black label) OS X disc, it should have the version number on it (e.g., 10.1.4, 10.2.2, 10.4.6, etc.). It it's the model-specific disc that originally shipped with the eMac, then there's something about the OS X version number and "eMac" in very tiny print on the label.
It's possible that the seller gave you the original OS X disc that came with the eMac, but that at some time the original owner upgraded to a later version, say from 10.2.x to 10.4.x Because of changes introduced to disc formatting with OS X 10.4, you can't go back to an earlier OS X version without doing an Erase and Install. Or, if the original OS X disc is for the 10.1.4 taht came with eMacs during the first few months on the market prior ro the release of 10.2, one of the missing features in 10.1.x was the ability to do an Archive and Install --- the only way to reinstall 10.1.x is to erase the hard drive and start from scratch.
If you don't have the Applications CD that came with the eMac, an Erase&Install could prove troublesome. You may want to consider investing yet more money into your purchase, and get the Tiger OS X 10.4 retail install disc. My own experience is that a first-generation 700 MHz eMac with 640 MB RAM is still respectfully quick, especially running 10.4, which is much more responsive that 10.2 or earlier. Your 800 MHz eMac with 1 GB of RAM should do quite nicely running 10.4. You can use the tips in Gulliver - Tiger Upgrade Guide.
One possible complication: some early eMacs came with a CD-RW or CD-ROM only, with no DVD-ROM or DVD-RW ability, and Tiger 10.4 is only sold as a DVD. Apple used to have an exchange program where for something like a US$10 handling fee, you could exchange the Tiger DVD for a set of CDs (7 or 10 CDs, or something like that), but the website offering the exchange program has been taken down after the program had been extended six times. There have been reports of users successfully getting the CD exchange by calling the Apple Store and getting a live operator, then asking if there were any copies of the CD exchange set still available --- Apple had some sets left in the supply chain when the exchange program finally ended, and they were unofficially still available a few months ago at least.
Or you could pick up a Firewire external DVD-RW drive for around US$100 and boot the OS X Install disc from that using Startup Manager.

Why won't the program fully open?

I bought Adobe Premiere Elements 8 a while ago but have lacked a computer that could handle it properly. I recently bought a powerful laptop so I installed Premiere Elements 8 right away, hoping to edit some videos. Unfortunately for some reason it can't open fully. I will choose a name and destination to save the project but when I try to actually work with the program it freezes on me, not telling me what is wrong.
I have tried uninstalling and reinstalling to the same result. What can I try?

How much free, clean, freshly defragmented space is on your C drive? Brand new computers can be a mess of fragmentation and temp files. First, ensure you have at least 20-30 gigs of free space. Then run this free program to clean things off:
http://www.iobit.com/advancedsystemcareper.html
Then defragment your drive.
Also, manually go to Windows Update and ensure you have even the non-critical updates. And go to Apple.com and ensure you have the latest version of Quicktime per the program's requirements.
If it still won't open, please provide us more information about your computer including your operating system, your processor speed and your RAM load.

Why won't my vi run outside of the LV2011 project explorer?

I've created a LV2011 project. The vi's within this project open executables to perform measurement functions. When I open the vi's from within the project explorer window the executables open with no issues. However, with the LV project closed and opening the vi's from "windows explorer" the executables won't launch. It seems like I need to have the LV project explorer window open. However that does not work very well in a manufacturing environment. What is the dependency relationship of running vi's in or out of the LV project? How can I remove this dependence?

crossrulz,
Good point. Nice to run executables and I agree. In a perfecct world thats what would happen. Do you know what the constraints are for vis in a LV project? Here is the error:
Error 1172 occurred at Error calling method Class.Initialize, (System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
Inner Exception: System.Runtime.InteropServices.COM Exception: An error has occurred in the vi. More information may be available in the Windows Event log.

Why won't iTune 11 run on Windows 7 64-bit???

Starting 3 ior 4 weeks ago -ever since updating to iTunes 11, I have been unable to start iTunes. I have tried every suggestion in the support community posting (and a few that were not here) all to no avail. This involved many uninstalls (including components 1 at a time), reinstalling as a package and as individual components, updating, as well as uninstalling/reinstalling the .NET framework, and a number of other things. I did get access to iTunes for a short time by removing everything and installing V9.x.x, but this version would not allow me to access my wifes iPhone (she uses my iTunes - or did anyway.) Today I once again allowed an automatic update to 11, praying that it would work. Successful install, but will not run. I get the same Error 7 (windows 127) as before. The only difference is a different dll listed. I AM SICK OF THIS!!!
If anyone from Apple monitors these boards, could you please let me know when you are going to supply a good version of iTunes? You are about to lose not 1 customer, but four, including my wife and daughters, as well as iPhone users, as we will be switching to android phone at our next wireless renewal.

Many thanks again.
The procedure entry point FigSubtitleStringCreatePropertyList could not be located in the dynamic link library MediaToolbox.dll.
That's a less common one ... so we might be looking at incidental damage to an Apple Application Support program file rather than something specifically 11.1.4.62-related.
Restart the PC. Head into your Uninstall a program control panel, select "Apple Application Support" and click "Repair".
Does the repair install go through okay? If so, can you launch iTunes without the error?

Why won't AcrobatPro_11_Web_WWMUI.exe run on my computer??? Please help

I was previously using Adobe Acrobat XI with no issues. All of a sudden on Sunday something crazy happened to my computer and the mouse had a mind of its own - started opening and closing things all the time, right clicking, jumping around etc........
Anyway....... ended up having to go back to factory settings and I cant get my Acrobat Pro XI back now!!
Went to the Adobe site, got the download assistant

The file that I go to, AcrobatPro_11_Web_WWMUI.exe WILL NOT RUN ON MY COMPUTER???
Sorry for the caps but I am so frustrated :-(
When I double click on it to run it, I get "This app can't run on your PC. To find a version for your PC, check with the software publisher.
I have tried with the antivirus turned on and turned off. Same result. Plus I tried to right click and then selected Run as Administrator. Looked ok, but then I got a message stating that Windows cannot find'C:\Users\ME\Adobe Acrobat XI Pro\AcrobatPro_11_Web_WWMUI.exe'. Make sure you typed the name correctly, and then try again.
I am on Windows 8.1 - please help me!!
Thanks in advance :-)

Hi,
You can download acrobat from here:
Download Acrobat products | Standard, Pro | XI, X
Make sure if there is any uninstaller in control panel --> programs then uninstall it before installing.
You can also download Acrobat cleaner tool to clean the application before uninstalling.

Why won't my programs start properly when I install 6u12 - 6u14?

Hello all
I'm not sure if this is the right place to post this, but I'm having some frustrating issues w/ programs after I install update 14 (I tried 12 and 13 too).
This is a confusing story, but basically I have this issue where programs seem to start properly (this includes Netbeans and an application that I've developed and try to run w/in Netbeans) but the interface components never totally paint themselves. I see the program as running in the bottom program bar, but I cannot do anything w/ the program. I've been messing w/ settings, but I cannot completely trace/solve the problem. What I DO know is that if I fall back to version 1.6.0_04, all my programs work fine.
Any thoughts? I'm hesitant to deploy a new version of our application w/ the latest Java version at this point.
Thanks for any help
Brent

The only consistent problem posts I have seen involve 14. And there aren't really a lot of those.
You might have some unusual situation. Or the cause might be something completely bizarre.

Why won't these files run on my Archlinux?

I wasn't really sure which category to post this in.
Anyway I'm trying to run the files in the bin/ directory of the archive I've uploaded here:
http://www.filedropper.com/jaglinuxtools
On Archlinux all I get is:
bash: ./aln: cannot execute binary file
and so on for the other three files.
I can boot up a live CD of another Linux distribution (kubuntu in this case), mount my Linux partition, and run the files from the same directory, and they all behave as they're supposed to.
What's the deal here? I'm sure my permissions are set up correctly in Archlinux. I've chmodded the files with an a+x on my machine and I even setuid/setgid on the suggestion of someone from the Atari Jaguar forums. That archive has the original files with unmodified permissions, by the way.
Anyone have any clue why this isn't working on my Archlinux? Does it work on any of your Archlinux setups either?

Actually come to think of it, back when I was running i686 the files did work the first time I used them, but I did a pacman -Syu shortly afterward and after that they started giving this error about not being able to execute them. It would make sense if the official Archlinux kernel options were changed to exclude this type of binary between my upgrades at that time.
