Loading files in browserlab hanging up.

Hi I was trying to use browserlab for the first time, and as it was "loading" my files, it seems to be hung on one jpg file. It's
just a button image, so its not a big file, but I dont know why it would hang up on loading that file. Any ideas as to what might be happening?

Ok, thanks for the info. It sounds like what's happening is that you're telling BrowserLab to preview from your server, but your site isn't public so we can't get to the content.
In the BrowserLab extension in Dreamweaver where you click the preview button, there should be a dropdown next to it. Open that dropdown and choose "Local/Network" rather than "Server". This will let DW upload your content to our servers so that we can take the screenshots. Once you've clicked the preview button, make sure you stay in DW for a while as first time you do this for a site the extension may need to ask for permission to access and upload your files.
Let me know if that takes care of the issue for you. If not, we can try to dig deeper and figure this out.
Thanks,
Mark

  • Windows 7 install hangs at "Windows is loading files ..." on MBA

    I have been trying to install Windows 7 Ultimate but each time the install hangs at "Windows is loading files ..." on reboot. I am using a Windows install DVD using an external drive. When the install hangs, the DVD is not being accessed. I have tried several times and it leads to the same result. I have tried different partition sizes (20 GB - 50 GB), no luck.
    Any help would be greatly appreciated.

    Solution
    I have a macmini bought in mid2011 with OS Lion on it. AS it doesnot come with an optical drive, I bought an LG DVD drive and used the windows 7 (64bit) installation DVD. It stopped at windows is loading files....
    I tired couple of other options like using flash dirve but it dint work.
    The I went to Apple's Genius Bar, and they put the installation dvd into their dvd drive (by Apple). Then the windows installed perfectly fine.
    When asked they said it must be the problem of DVD and I found out that it actually is the cause. Apple products require dual layer optical drives but in general the optical drives we buy can only read single layer dvds. So I got to fix the problem by borrowing their dvd drive in genius bar and now i m good to go.....
    Hope this helps

  • Load Files into Photoshop Layers hanging...

    I have both Bridge CS5 4.0.4.2 and Photoshop CS5 12.0.2 x64 open and running on a MacBookPro... when I highlight a few files inside of Bridge CS5, then go to Tools, Photoshop, Load Files Into Photoshop Layers, when those files start opening in Photoshop and stacking as Layers, the process just hangs and stops processing after the first Layer is placed - any ideas why this happens, or just a bug? Thank you!

    any ideas why this happens, or just a bug?
    As I can’t reproduce the issue so I would assume it’s not a bug per se.
    Have you tried trashing prefs for Photoshop (after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed)?

  • Windows 7 Professional PC hangs at "Loading files" when trying to boot with custom capture image on Windows Deployment Services.

    I have created a custom capture image in WDS. Now when I try to boot my reference PC into this image the PC hangs at "Loading files". The reference PC is running Windows 7 and I am using Windows Server 2012 Standard on my server.
    I have followed the instructions on how to create the custom capture image on the server to a fault. I PXE boot the PC and it shows the capture images after I hit F12. The problem is that it starts to boot and then hangs about 2/3 way through the progress
    bar.
    Any help would be appreciated.

  • Boot Camp / Win 7 (64-bit) install hangs at "windows loading files"

    I was hoping I might get some help from the community. I've got the new MBP 15", 2.66/i7 and OS 10.6.3. I launch Boot Camp utility, assign a partition for Windows (76 GB in this case), insert the Win 7 disc (Home Premium 64-bit OEM I just bought) when prompted, and the laptop restarts.
    It asks me to press any key to boot off the CD/DVD (screen color is blocked a bit oddly, but no worries). I press a key, screen goes black, and the message, "windows is loading files" appears. The white status bar below it progresses from the left all the way to the right, and then the whole process freezes before going to the next step.
    I found another person's solution post on this here:
    http://forums.macrumors.com/showthread.php?t=703045
    I haven't tried it yet, because I don't understand if I have too format the whole drive or just a partition. I don't understand his solution completely, so I was hopeful someone could tell me if it even sounds like it might work or if there is another known solution.
    Thanks!

    Thanks for including the details. Up front even better. Two different makes? AMD and Nvidia do not play together in Windows. 2 'extra' means 3 GPUs. Now there I would look at leaving just one.
    What I meant to say was just leave the one drive where Windows will go, no other drives present - pull those sleds. And put Windows in bay #1.
    Slowest burn speed, which is usually 2x but if 4x is the slowest setting, fine. Odd behavior and bad installs even when it does appear to.

  • MDT 2012 + WinPE 4.0 + VMWare ESXi - Hangs "Windows is loading files" booting into PE

    I'm trying out using MDT 2012 and WinPE 4.0, upgrading things. I've recreated things following templates in MDT 2012. I'm also using ADK and WinPE 4.0.
    Issue I'm seeing is upon restarting into WinPE I see the screen showing Windows is Loading Files and the progress bar. I see the first one load through and then the second slower one load through. Once progress bar fills, it just does nothing and I'm left
    looking at a complete progress bar.
    I was trying obviously first using VMWare ESX 5.0 with no success, subsequently tried a couple of physical machines and those had no problems. I still want to get working on ESX since that will help speed up development and testing of the rest of the stuff
    I need to upgrade. Tried a variety of SCSI controllers within ESX vms. I tried VMWare Workstation 9 with the mixed results as with the LSI Logic Parallel SCSI controller had success but not the others.
    I of course at first tried making sure drivers were added with no change, although that still could be an issue with drivers I found to put in being incorrect.
    More interestingly though is that I can of course install Windows 8 from install media just fine on these hardware, as well as if I create an ISO from the deployment share and boot to that it works just fine, so it seems to just be an issue when booting
    to WinPE on disk.
    Any ideas are greatly appreciated. Thanks.

    I did have the same problem with ESXI 4.1 and Windows 8.
    I found a full solution with the following:
    download the linked file at the bottom of this post and add the following options to your vmware-configuration
    file:
    bios440.filename =
    "<full path to rom image>"  --> if file in folder of vm only "bios.440.rom
    mce.enable = TRUE
    cpuid.hypervisor.v0 =
    FALSE
    vmGenCounter.enable =
    FALSE
    This worked for me for several environment with an older ESXI-invironment and Windows 8.
    http://communities.vmware.com/servlet/JiveServlet/download/2139717-98102/bios.440.rom
    I can confirm that this works also!  Many thanks!

  • WDS capture stuck at windows is loading files image.wim

    Hello,
    We have a new Dell XPS 13 that I have built up for Windows 7, I want to capture the image using PXE boot to our server.
    However, after I press F12 and get the the screen "Windows is loading files..." the screen seems to just hang at one point with the text below "IP: 192.168.3.252, File: \boot\x64\Images\capture image.wim"
    Any suggestions would be great.
    Thanks
    Ash

    You are best posting this to a WDS forum as ConfigMgr does not use the capture image methodology that native WDS does. Speaking of which though, why are you using native WDS instead of MDT? MDT is far more powerful and is actually easier to use than native
    WDS.

  • "Load files into Photoshop layers" fails to complete CS6

    Hi all,
    Hoping someone can help with the folling problem with Photoshop & Bridge CS6
    When in Bridge, after selecting 6 images (CR2) using the command TOOLS>LOAD FILES INTO PHOTOSHOP LAYERS the first file will load into Photoshop, Photoshop will then generate a second blank layer and then read the second file. At this point the "script" will stop. I am left with a document with 2 layers. The top layer has my first image, the bottom layer is empty.
    At this point when I quit Photoshop I am prompted to save this open document which appears to be the only open document. I choose not to save this as a file. I then get a dialogue box prompting to save another open document. Photoshop has loaded the second file to place as a layer but as the "script" has aborted I am left with an open, but invisible file.
    When I first loaded CS6 on Snow Leopard, it would demonstrate this behaviour every time I attempted to run this command from Bridge.
    I did a clean install on a blank HDD of OSX Lion. Installed CS6. The command worked without fail for about a month.
    Then I would get the command aborting occasionally. Restarting Photoshop would let me continue for a few hours before this aborted script problem would happen again.
    Over the last week it has become more frequent, to a point where this workflow is unusable.
    A restart of Photoshop may fix the problem for the next batch of images, only to fail again soon after, or fail on the first attempt after a relaunch of Photoshop.
    A reboot of my computer will allow my to load one or two sets of files before again failing to complete the command.
    I have tried the following:
    In Photoshop preferences:
    disabling the "Use graphics Processor"
    Increasing or decreasing the amount of RAM available to Photoshop
    Changing the cache levels or changing the cache tile size
    changing the scratch disk
    Trashing the Photoshop preferences file (Photoshop Settings.psp)
    In Bridge
    Purging the cache
    Increasing or decreasing the cache size
    Resetting Bridge preferences (holding Command on launch) and deleting all cache files.
    In general system
    Quitting extra programs (Safari, Thunderbird, iTunes)
    Sometimes this will seem to then allow Photoshop to load a full set of images, only to abort again after a few sets.
    Rebooting the computer - again will work for a few images sets before again failing.
    Now the fact that it worked fine for several weeks without presenting a problem would indicate that it is not a bug.
    The fact that is slowly started happening then became more frequent would indicate something changing slowly over time - a larger cache folder perhaps, although purging known Bridge cache folders has not filed the problem.
    Really at the end of my tether here. Even considering downgrading to CS5 - but don't want to have to use the older Adobe Camera Raw.
    System is as follows:
    Mac Pro 2 x 2.66 Quad Core
    24GB RAM
    ATI Radeon HD 4870 512
    OSX Lion 10.7.4
    I have seen a couple of others have posted having a the same problem, both with CS5 and CS6.
    Hoping someone has an answer.
    Thanks.

    Hi JJMack - I just re-read your post. For some reason I thought you were suggesting to make sure "Open documents in Tabs" was selected, it was. Now I realize you were suggesting to turn it off! As another attemp to solve this problem I did de-select it today. Seemed to work for a good while. I was getting very excited, then, on the last set of images I had to do it displayed the same problem. But, it did go for quite a while without failing, and when it did I was thrashing about trying to make another app active. When loading documents like this - with "Open documents in Tabs" de-selected, Photoshop wants to put the loading images as the front-most window, no matter what other apps (Bridge, email, web etc) I click on in the dock. I think it is related to the bug you described effecting the "load files to stack" command.
    Hopefully Adobe is looking at this - mind you, I have read reports of people having this problem in CS5! Looks like that was never resolved sadly.
    I'll keep testing and post back.
    I am looking to upgrade my video card to see if it's a video memory thing.
    What is very weird though is the fact that this problem didn't present itself until after several weeks of working with this command with no problem. No additional apps installed, nothing changed. Why would it start happening only after a while?
    Thanks again for your suggestion.

        From what I understand from your log file, this is a custom import package. It is failing into the last step, loading data into the cube and it seems there is no file to be loaded. If the same package is working well for the other users, this means that the user has not enough security rights to load data from that file (maybe the file contains data for which the user is not authorized to see).
       To understand better what is happening, just try to activate the debug using the DEBUG(ON) instruction into EvModifyPackage. This will create more information regarding the parameters passed to your tasks and you will be able to identify the file name passed to Dump&Load task.
    You can verify then into Private publication\user name\Temp files the content of file (and the content of all temporary files generated by your package) and this will help you to understand where is the problem.
    Hope this can help you,
    Mihaela

  • Could not load file/URL (file not found) error for JNLP file

    I am completely baffled in trying to figure out why I am getting the following error for some JNLP files but not others:
    Error: could not load file/URL specified: C:\Users\tom\AppData\Local\Temp\javaws2
    java.io.FileNotFoundException: C:\Users\tom\AppData\Local\Temp\javaws2 (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)

    at com.sun.javaws.Main$1.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)I have Googled around this forum and elsewhere, and have seen reports that this error is IE-specific, and seems to have something to do with no-cache headers being sent, or with the client browser's cache being full or turned off (which is not my case). I saw the information in the JavaWS FAQ, which recommended turning off security constraints for the JNLP's URI. I tried that, and it didn't help. One of the very baffling things is that I have created several variations of the JNLP file, with varying combinations of jars and property resources, and some combinations always work while other combinations never work. Here's an example:
    <jnlp spec="1.0+" codebase="$$codebase">
       <information>
          <title>demo app</title>
          <description>illustrates weird bug</description>
       </information>
       <resources>
          <j2se version="1.5+"/>
          <jar href="randomFile.jar"/>
          <property name="xxx" value="xxxx"/>
          <property name="swing.metalTheme" value="steel"/>
       </resources>
    </jnlp>The above file always fails with the error shown at the top of this message. However, if I remove either of the two properties, it works fine. And I have created other variations with lots of properties, some of which work. All of these variations are in the same directory in the war file, served by the exact same servlet (a slightly modified version of the jnlp.sample.servlet.JnlpDownloadServlet provided with JDK 1.6.0_3). Assuming that a no-cache header is the problem, what on earth could be causing some JNLP files to always be served with a no-cache header, while others are never served with a no-cache header?
    On a related note, any recommended debugging techniques for seeing what headers are being transmitted? I tried adding a simple check for a "debug=true" parameter in the servlet that causes it to set the content type to "text/plain" instead of JNLP, and that allows me to see (rather than execute) the JNLP XML that's being returned, but it doesn't show me the HTTP headers that are being sent back. If any caching headers are being set, I think it must be being set by the servlet container itself, as it's nothing being set in the servlet code that I can see. So I don't see any way on the server side Java code to output or log the actual HTTP response (or is there?). Any tips in that regard much appreciated.

    Hi Luca-Sanna,
    Thanks for the response. Re browsers, yes, it fails in IE but it succeeds in Firefox. The info on the JavaWS FAQ and other places all seem to indicate that it's an IE issue concerning handling of the cache-control headers.
    I should check in my webserver forum (Sun WebServer 7) to see about logging options. Sniffing on the client side is not possible, as my app is required to use HTTPS exclusively, and unfortunately that also precludes a telnet GET request.
