    Hi, Isn’t possible to make the installer to overwrite the old one? While I have tried to install it with other packages, before I have found this.
    And can you also make a installer for smbclient extension?

      Haven’t received many requests for smbclient, but may look into it.

      Not knowing how you installed MCrypt, it is difficult to recommend what to do. In any case, if you remove the reference you added to your php.ini file, you can keep the version that is not working and use our installer.

    The MCrypt installer doesn’t modify a system when the MCrypt module is already loading.

    The installer does a simple test:
    php -m | grep -i ^mcrypt && echo Installed || echo Not Installed

    A clean-install can be forced by removing any mcrypt lines from /etc/php.ini

      I have check it with your command but not installed.
      I have check it many times over php -m but without any changes.

        Jeff Johnson says:

        Alfista – Please create a folder on your desktop named ‘debug’ then run the installer again.
        The debug folder will contain more detail about the installation.

    I tried installing using Mcrypt installer, however, I never go beyond the disk part. I get a message that say ” Roundcube can’t be installed on this disk.” Is it because I don’t have enough space? I have 304.69 GB available currently. I’m running on Yosemite 10.10.5. Any insight is appreciated!

    • Jeff Johnson
      Jeff Johnson says:

      When our Roundcube installer is udated from 1.1.4 to 1.2 then mcrypt will likely be removed from the Roundcube Installer.

      The topicdesk mcrypt installer and mcrypt install tutorials on other sites are very popular, obviously there is interest.
      People do require and do install mcrypt, our package simply automates the process.
      Taking our own personal time and resources to package a product for the benefit of others – thats a disservice ?

        Jeff, sorry for my choice of words, of course the time and effort you provide is a service to the community!

        Do you agree with the links above, that mcrypt is abandonware?

        • Jeff Johnson
          Jeff Johnson says:

          Why are you asking me ?
          Its up to people that use mcrypt to determine its value.
          If you don’t care for it, then move on.

          We provide an automated installation for those that need it – thats it.
          Discussions about the installer belong here.

            Sean says:

            Question about your installer then: what version of mcrypt does it install? Could you give the URL of the code you built from?

    • Jeff Johnson
      Jeff Johnson says:

      The mcrypt installer is a byproduct of our roundcube installer.

      Roundcube no longer requires mcrypt, so we have no plans to update the mcrypt installer – in fact mcrypt will be removed in our next roundcube installer.
