  • Cannot install Photoshop CS6 ugrade to Photoshop CS4 on Windows 7 PC.

    I cannot install Photoshop CS6 upgrade to Photoshop CS4 on my Windows 7 PC. Error reads - Serial Number you provided is valid, but a qualifing product could not be found on this computer. I then selected CS$ as the product and entered the serial number with Error - This serial number is not for a qualifying product. CS4 is currently running on the PC. Any advise?

    If you recently purchased CS6 as an upgrade then the versions that qualify for the upgrade were reduced a couple years ago to only include CS5 and CS5.5.  If you purchased CS6 a couple years ago while CS4 was still in the upgrade path then you should contact Adobe support using chat and see if they can help you get thru the activation.

    photoshop cs6 error "could not use the type tool because the target channel is hidden.  happens when im typing in photoshop, go to another layer and then come back. can't alter text at that point.  i really need to get thsi figured out. thank you.

    You may have answered my question. I AM using the 64bit version of Illustrator CS6. I had no idea there were bugs in it that affected paths copied and pasted from Illustrator to Photoshop.
    A bit more about what I'm trying to accomplish... I'm trying to follow Deke's tutorial (http://www.deke.com/content/dekes-techniques-018-creating-a-3d-pie-chart) which is already difficult since so much has changed between CS5.5 and 6, but then on top of that, I keep getting errors!
    So I created the pie chart exactly as he shows and copied and pasted into Photoshop exactly as he does. Before submitting this post, though, I tried drawing just two very simple triangle shapes, copying them both and pasting them into Photoshop as a shape layer. The shapes weren't overlapping, but they were a part of the same shape layer just like the pie chart tutorial.
    Thanks for your help. If there is anything else I should try before just giving up because of the 64bit bugs, please let me know.

  • Cannot use PhotoShop CS6 after trial expired, even after purchasing Creative Cloud Student Edition

    Hi.
    I had PhotoShop CS6 trial, which expired.
    I have purchased Creative Cloud student edition, I receive a message that my PhotoShop trial has expired.
    I am prompted to purchase the product to extend it, or type in the product's serial number
    (I never received a serial number.)
    I paid for Creative Cloud and have an order number, I should not be having this issue. 
    I have uninstalled and reinstalled PhotoShop CS6 multiple times, I also use DreamWeaver and am fearful that I will encounter the same issue. How can I use the Photoshop CS6 after I have paid for it?

    Hi.
    The trial expired 2 weeks ago - Monday.
    I purchased the Cloud Yesterday, also 2 weeks ago Monday 10/15/2012.
    I purchased it twice thinking 1 purchase did not complete.
    I still will need to request a refund for 1, I've been too busy between, work, school, and kid. I'm at work now.

    I just bought a new Mac Book Pro and did a migration of the content of the old laptop (also a Mac Book Pro) to the new one. Now I cannot start Photoshop CS6. When I am starting it I have a window "Adobe photoshop CS6 extended" opening requesting a connexion. When I am entering my password for the connexion the software crashes. How can I fix the problem?

    Migrating, transferring or copying is DEMANDING trouble, not just asking for it.
    Always install from scratch, from the original media,

  • I cannot get Photoshop CS6 to download to my new computer

    Why can't I download Photoshop cs6 onto my new PC?
    I have the original Photoshop CS3 disk which has been upgraded online to CS6 with new serial number. I could not find any way to download either a trial or the programme I bought.
    My new computer is Windows 7 64 bit. If I deactivate Photoshop CS6 on my old pc will that work?

    You have a maximum of two CS6 activations. If you have already used up that quota,you must deactivate one before installing on a new PC.
    Use this link to direct download Photoshop CS6. Follow the instructions carefully or the download won't work.

    Enter your CS6 serial to convert this trial version into a paid one.

  • Cannot find Photoshop CS6 even though updater informs me it is up-to-date.  OX S 10.9.1.

    Cannot find Photoshop CS6 even though updater informs me it is up-to-date.  OX S 10.9.1.
    I go to updater and it says that it is up-to-date, even though I have uninstalled it.  When I try to reinstall, the download button is available, I click it, which takes me to the updater screen, and informs me that it is up to date, even though it is not in my application folder.  I have ben able to download Lightroom with success, but not Photoshop and other previously downloaded apps.

    Chin Chin please see CC desktop lists applications as "Up to Date" when not installed - http://helpx.adobe.com/creative-cloud/kb/aam-lists-removed-apps-date.html for information on how to resolve your current difficulties.

    Have you updated your iTunes on your computer? WIth a device running iOS7, you need iTunes 11.
    When you removed iTUnes, did you see something named 'apple mobile device support' or something like it? (The exact name varies from operating system to operating system). If you see that, uninstall it too. That's the drivers for your iPhone and they should self-install when you plug your device in.
    If all that is fine, have you checked your cable and USB port? a malfunctioning cable can keep you from syncing.

  • When I try to open a .jpeg in Bridge CC2014, I get the error message cannot find Photoshop CS6.

    I have associated my .jpegs with Photoshop CC2014. I had to do this manually. Now, every other program opens them in Photoshop, except Adobe Bridge CC 2014.
    If I try to Open a .jpeg (or any other file associated with Photoshop) Photoshop from bridge, it says It cannot find the photoshop cs6.exe file. Of course not! I uninstalled it before I installed CC. Maybe two years ago. And now Bridge CC2014 goes looking for that as the CS6 default Photoshop.exe? 

    I finally got it to work by going into Bridge->Edit>Preferences>Default settings. After choosing a file that is supposed to open in Photoshop, I chose to change it and browsed to Program Files>Adobe>Adobe Photoshop CC2014 and manually linking each filetype to the photoshop.exe.
    I have spent the better part of a week getting Adobe software to work again after the Adobe CC2014 install. I will never trust Adobe CC updates again. They failed to warn me that CC2014 installs as a completely different copy rather than an update of CC. As a result, I ended up uninstalling CC apps after installing 2014. A mess that has cost me more than *30 hours* of chasing around forums, manually re-associating files. Even a registry hack! Found by a user, not by adobe.
    Ordinary users shouldn't have to do this sort of thing after a normal install from the Creative Cloud panel.   The genius software engineers at Adobe are being totally undercut by the keystone cops in the cc updates and install department.
