Invalid Checksum error on PS CS6 beta install

I'm receiving the following error when I try to mount the beta dmg:
Running OS X 10.6.8. I've redownloaded twice, but it has not changed. Ideas?

Others are clearly installing it successfully, so you're clearly getting corruption in the file during download.  It's a BIG file.
Check all the components of your network, but it's possible something in the network outside your control is at fault.
Have you compared the downloads you've received each time against one another?  It would be telling if you were to find them different from one another.

  • Invalid Checksum Error for Photoshop Elements 10 installation

    I have tried installing Photoshop Elements 10 on my Macbook but I got an "invalid checksum" error (saying that the following disk images couldn't be opened).  Was there a previous solution to this type of problem?

    That response is not at all helpful.  I have no idea what you were referring to, but there is no pale yellow bar at the top of the forum when I am looking at it now.
    In the future, consider posting a URL or something else that will continue to be relevant and useful in a persistent way.  Perhaps typing a sentence or two about what's going on if you know.  If it seems obvious to you, that doesn't mean it will be in the future to others having the same problem.

  • 'Invalid Checksum' message when I try to install MS Office 2011 on OS 10.9.1

    I am trying to install MS Office for Mac (365 University), I have now downloaded it 3 times, once each with Chrome, Firefox and Safari; each time I get the 'invalid checksum' error msg when I try to install. I am using Macbook Pro Retina w/ OS 10.9.1

    Yes this is what the Microsoft person said on the phone. I don't understand why it would be corrupted every time I download it, at different times of day with different browsers, wifi and ethernet, and my partner even tried with her windows machine and i got the same result after transferring it by usb to my computer. Also why does this only happen with this dmg and this OS whereas I've been downloading and installing many programs without issues.

  • "invalid checksum" error downloading Photoshop 5.1

    How do I solve this issue? Have tried downloading Photoshop 5.1 numerous times and keep getting an invalid checksum error when it completes and wont launch ... Also at this point the extracting bar on the download manager just freezes.

    And more specifically? Operating system? Browser? System specs? Could be an issue with temporary disk space required for the extraction, could be that some security tool is interferring, could be that your network connection produces errors... Impossible to even guess without more info.

  • Disc Space error on Photoshop CS6 Extended install

    I am attempting to install Photoshop CS6 Extended (win version) on my Windows 7 ( 64 bit) machine. Core 2 duo CPU @3.16gh with 8 gb or ram.
    The machine meets all the minimum requirements and has more than enough disc space.
    This is the error I get during initial extraction. "A problem occured while extracting some files. Check available space on your computer and write privileges on the destination folder. "I am the admin, the folder has permissions set correctly.
    Also, I tried to read the "installation instructions" found in the CD and am unable to read the file as it says it is corrupted. Anyone else running into this issue?

    if that's a problem with your cd, download a trial of ps cs6 and install/activate using your serial number: 
    if you follow all 7 steps you can dl a trial here:  http://prodesigntools.com/adobe-cs6-direct-download-links.html
    and activate with your serial.
    if you have a problem dl'g, you didn't follow all 7 steps.

  • Photoshop CS6 Beta install failing on Windows 7 Ultimate (32-bit)

    I am using Windows 7 Ultimate (32-bit). I am unable to install the Photoshop CS6 beta version. When I launch the setup.exe file, the "Initializating Installer" dialogue box appears, however as soon as it finishes loading the dialogue box closes and nothing happens after that. If I try to relaunch the setup, it prompts me by saying that another setup is in progress. Could you please help me in this regards?

    Hi Pragya,
    I have done so several times as well. In fact, I just tried it a couple of minutes back, still the installed initializes and disappears like nothing happened. In the mean while I have restarted my machine a number of times.
    Can anyone help me with this issue, as i really wanna try the new CS6? Its really annoying.
    Thanks!

  • Error when opening CS6 Beta

    I downloaded CS6 and when I double click to open the dmg file, I get the error photoshopcs6_p1_mac_no _mountable_file systems.  What should I do in order to be able to open the application?

    I didn’t have any trouble installing it .. Only when I open it to use it.. I’m thinking it might have been one of the plug-ins that I transferred from CS5 .. The migrate didn’t work so I copied the folder contents and pasted them in CS6 so I don’t know which one it might have been.. The reason that I think that is because it  said  could not load Fastcore Routines It does not work in this version also the Multiprocessor support Module does not work in this version...
    I have a home built 64bit quad and more ram and space that can even use... and it even has extra bays to add additional memory or other disc as required...  I run windows7 Ultimate..
    Thanks,

  • Session State Protection invalid Checksum errors show valid checksum

    Hi,
    I am investigating Session Sate Prtection to let me make my appications more secure.
    I have created a simple Report / Form pair that allows me to open an item for edditing.
    I have set the Application to Session State Protection 'Enabled' and and my form page to Page Access Prtection 'Arguments Must Have Checksum'.
    From my report page I click on the edit icon for a row and I get the edit page with the url:
    f?p=126:3:7115846938209895::::P3_WORK_PACKAGE_ID:1179&cs=3CC0C97D3A8B114D2E40EDF158C0AECFB
    If I then manually manipulate this url, to change my P3_WORK_PACKAGE_ID from 1179 to 1180, to:
    f?p=126:3:7115846938209895::::P3_WORK_PACKAGE_ID:1180&cs=3CC0C97D3A8B114D2E40EDF158C0AECFB
    I get an error of:
    Error The checksum computed on the request, clear cache, argument names, and argument values (P3_WORK_PACKAGE_ID1180 [01BE394775DB7B5A861BEA77B6637A46] ) did not match the checksum passed into the show procedure (CC0C97D3A8B114D2E40EDF158C0AECFB).
    All well and good, but it tells me what the checksum should be. I can now update the url to use the displayed checksum to make the url:
    f?p=126:3:7115846938209895::::P3_WORK_PACKAGE_ID:1180&cs=301BE394775DB7B5A861BEA77B6637A46
    the form opens for P3_WORK_PACKAGE_ID 1180.
    How do I stop the error message telling my how to bypass the checksum security?
    Thanks,
    Martin

    I am not sure but maybe this detailed message is coming if you are logged in to Apex and otherwise it is showing more general error message with no checksum?

  • When i try to open the master collection i get a error message saying invalid checksum

    when i try to open the master collection i get a error message saying invalid checksum

    I'm trying to install Adobe Photoshop Elements 10 (English North Americas) and have the same problem.
    #1 the default location is in some Local / User folder and I too made it the Application folder. Now Adobe Download Manage will only download to Applications folder. The first time the installer failed I logged out, but the installer .dmb was erased. Second download I copied to the Desktop, and deledted the orgional in the Applications folder. BOTH .dmg had checksum errors. BOTH failed on install. Restart of systm changes nothing
    I'm on Cable and am able to download 20G files without issue. (I work with 1080i/p movies all the time). MacOS 10.7.4 MacBook Pro 2.2 i7, 4GB, 200GB free space
    As someone who has used Adobe products since before Photoshop v.1 was released, this would be far from the first bad Adobe installer!

  • Uninstalling, then re-installing the CS6 beta trial on the same Mac  

    My inquiry is really simple:
    Can anybody authoritatively confirm that it is possible to uninstall the CS6 beta trial, then re-install it on the same Mac and it will continue to work as when you first installed it, before the uninstall.
    That's all.  Forget about any other version of any other software being installed or not.
    This was not possible with previous trial versions, as the trial would expire instantly upon uninstalling it.
    I'm starting a new thread to get away from any confusion.
    Thank you.

    Thank you again, Pete, and my thanks also to those who replied in my other thread.
    I did in fact uninstall the CS6 beta, installed Ps 12.1 ("CS5") upgrade without having a previous version installed, updated ACR to 6.6 then successfully re-installed the CS6 beta.  Everything is working fine.

  • Is it necessary to remove the Photoshop CS6 Beta before installing the trial?

    I installed the CS6 Design and Web Premium trial while I wait for my ordered update disk to arrive.  I have the PS CS6 Beta installed and I note that the trial installation did not install CS6 Photoshop or CS6 Bridge.  ????????????

    In the future please remove beta software prior to installing released versions of the software.  Presently I would recommend you uninstall not only the Photoshop CS6 beta but also the Design and Web Premium trials as well.  Once the software has been removed, including the beta, you can then try the reinstall again.
    Hopefully it will be as simple as this but if not please feel free to respond to this thread with any additional difficulties which arise.

  • Invalid Checksum when trying to update MAC OS X 10.6.4

    Hi all.  I own a 15 inch laptop mac i purchased in 2009.  I have recently realised that my MAC software has not been updating or installing correctly.  I tried to manually download the software 10.6.5 ( as i currently have 10.6.4) and it came back with an invalid checksum error.  I retried the download several times and got the same error.  I also tried other downloads and also got the invalid checksum error. (.DWG files).
    Another thing that seemed strange was that i had been trying to download 'star walk app' for my iphone and also a jamie oliver recipe app however these files seemed to keep restarting their download due to errors.
    I have done some research and the possible issues i have come across are:
    - possible internet connection error.  This doesnt seem to be the problem as i can stream youtube etc with no issues..
    - possible RAM error.  How do i check this is the problem without purchasing new RAM chip?
    - corrupt download.  Cant be this due to all my files being corrupt.
    Can anyone help me further with trying to solve this issue? 
    I have been so happy with changing to the Apple life and now i am starting to regret it as i am finding it near impossible to repair my laptop.... 
    Any help is appreciated, Thanks

    If you think your Mac is having hardware problems, I'd run the diagnostics that came with your Mac.  If the diagnostics came on a separate disc, run them by holding down the "C" key while booting with that disc in the drive.  If you only have one "system restore" disc, hold down the "D" key while booting with that disc in the drive.

  • INVALID CHECKSUM: Motorola SBG6580 wireless modem router and software updates (10.7.4)

    Tried to install 10.7.4 via software update dropdown on my MacMini over ethernet on my home computer network, failed.  Downloaded Combo Client 10.7.4 update from apple.com. Downloaded fine.  Failed to mount with invalid checksum error.  Tried to download on Win7 Dell laptop on my same home network via Wi-Fi, and copied to MacMini via USB flashdrive.  Copied ok, but mounting returned invalid checksum again.  Went to work, downloaded Combo Client 10.7.4 onto USB flashdrive, came home, copied it, mounted and installed just fine!
    So, kept trying to download Combo Client from apple.com on my home MacMini.  Kept failing, invalid checksum. Did this about 20 times during a few days, and actually got two of them to mount without the checksum error.  Realized that something in my network was failing, intermittently.
    Figured at this point it was either the Motorola SBG6580 modem wireless router or Comcast cable ISP service.
    Went to best buy and bought a new Motorola SurfBoard SBG6580.  Installed it, provisioned it with Comcast.  Took about 20 mins with Comcast pushing over the same new Motorola firmware that was released in MID FEB 2012.  I think it is 3.3.1.  Tried to download Combo Client and invalid checksum again. Installed a new Motorola SurfBoard SB6121 modem (which has a very different firmware BTW) and it download and mounted the Combo Client 10.7.4 update just fine!
    Realized it was the firmware that was causing it, not a broken modem.
    Comcast pushes over cable automatically new firmware that is given to them by Motorola.  Apparently no did a thorough check large DMG files that require a checksum and it is therefore somehow corrupting them when downloading.  Earlier this year the firmware was updated 3.1 to 3.3.1 then Comcast pulled it and downgraded all SBG6580 back to 3.1.  Then in mid Feb they reuploaded 3.3.1 firmware.  That is the one causing the problems.
    You can either wait it out till they push a new one that fixes it, and have all your large DMG files transferred from another internet connection and copy them over, or just get rid of that horrible SBG6580.  That is what I did and now using a Motorola SB6121 modem with a Cisco EA2700 wireless routher.
    Let me know if any of you are also experiencing this issue and if/when Comcast/Motorola will fix it.

    No, nothing custom that I did. Besides turning off the WPS thing as a possible security problem (we dont need it anyway) and setting the wireless passwords/SSID/channel stuff, everything is as it was factory or changed by Comcasts profile.
    It's obvious if you replaced the SBG6580 with a two-peice combo and the problem went away, that it seems to be with the SBG6580. Just weird to me becuase a problem like that would almost seem more like a hard disk or web browser problem. TCP/IP has a checksum/retransmission layer or protocol built in, if short or defective packets show up, they would be sent again.
    I mean I've seen like cheap 24 port 10/100mb switches running at 100% throughput, to the point they reboot. Anything connected to them stops or slows down but generally get going where they left off, unless the connection got severed.
    I'm just saying a bad iso or dmg file, had to had bytes changed or missing, like the web browsers buffer or a bad block write on the disk drive saving it. There was a lot of talk about the SBG6580 on dslreports and comcast discussion groups, would be interesting to see if anyone else mentioned it for that model.

  • Invalid Checksum when trying to use Seagate Backup Drive for Time Machine

    Hi,
    I'm trying to use a Seagate Backup Plus Drive with my Mac.  It was originally used with a Windows machine.  It does have the Seagate Dashboard Installer.dmg file.  When I try to install it, it gives me an "invalid checksum" error.
    I've also opened it in Disk Utility and attempted to reformat it into the Mac OS Extended (journaled) format, but it says it could not unmount the disk.  I cannot see that it has any opened files that would be causing this problem.  Any suggestions?
    Thanks!

    Tim,
    I just switched from Entourage to Mail (for many reasons). Thus far, I love Mail. You may want to get the Widescreen plugin for it if you like the three-pane configuration of Entourage.
    You should also be careful with Address Book if you have syncing set up in Entourage. In other words, probably should turn it off, along with any daemons you may have running. I lost data twice (once before my very eyes!) until figuring this out. Used Time Machine to restore a previous address book with all my contacts.
    Thanks for the other information on this thread. Since I should be upgrading my old external drive anyway, it will help in purchasing a new machine for use with TM.
