  • App Builder install-tried all the recommended fixes, but still does not work

    Hi all

    I've read similar questions others have had to install the generator of the app and tried the fixes suggested, but am still installation issues.

    I downloaded the latest version of the App Builder (32.4 I think), and am in Mac OS X 10.7.5. When I try to install I get the error "Sorry, year error has occurred." The application could not be installed because the Installer file is damaged. Try obtaining a new installation of the author of the application program.

    Just out of curiosity, I tried to install the same file on another Mac (OS X running 10.10.2) and installed without problem. If the installation file seems fine.

    Depending on the system configuration required, my 10.7.5 system must supports installation, so I don't know what else to try.

    Thanks, Louise.

    Ok. For assistance with this then, call the business support. You can find contact information by logging on http://digitalpublishing.acrobat.com/ and looking in the Middle at the bottom of the screen.

  • I really hate this version 23.0 requires me to have the band to tabs. I want to remove it. I tried to install version 22 of the archive, but it did not work.

    I rarely use tabs; When I work, I prefer individual browser windows. For a single window without tabs, tabs band is clutter and space wasted. Previous versions of FF has allowed me to remove the tape to tabs in the options. Now on v.23 I can't. How very, very boring.

    I tried to install the previous version, v.22, from the archives, but it did not work. I would be grateful a way to remove the band to tabs in v.23, or further instructions for down to v.22

    Thank you.

    The following may not be the only or most effective way to get the view you want, but that's what I saw recommended so far.

    You can ban the entire tab bar, or when only several tabs are open, by using a setting in the Tab Mix Plus extension.

    Please see this answer for more information: https://support.mozilla.org/questions/963676#answer-464257
