The steps to upgrading (or reinstalling) ImageMagick (on Windows) are:
1/ Consider suspending your Asset Bank (by stopping Tomcat). This step is not essential, however Asset Bank will show an error if any user performs any action that requires an image conversion while ImageMagick is being reinstalled.
2/ Identify the ImageMagick home directory, i.e. the directory in which it is currently installed. By default this will be C:\Program Files\ImageMagick. If not, check the ApplicationSettings file for the setting imagemagick-path – this will be set to the ImageMagick home directory.
3/ If you have previously reinstalled ImageMagick manually, i.e. since your initial installation of Asset Bank, then uninstall the existing version from the Control Panel. This step is not essential, but it keeps your ‘Start’ menu tidy (otherwise you will see multiple versions of IM in it).
4/ Download the the installation files for ImageMagick. We currently recommend version 22.214.171.124which can be downloaded here:
FYI, if you want a later version than the one we recommend then the latest version of ImageMagick can be downloaded from: http://www.imagemagick.org/script/binary-releases.php#windows
You will usually want the ‘Q16-windows-dll’ version.
5/ Run the installer and following the prompts to install ImageMagick to the home directory identified in step 2 above. This usually involves changing the directory suggested by the installer to remove the version information from the directory name.
NOTE: When installing ImageMagick 7 or above you must select the "Install legacy components" option otherwise Asset Bank will not function correctly
6/ Start Asset Bank if you stopped it in step 1. If you didn’t, you don’t need to restart it unless you changed the ImageMagick home directory (and therefore the setting ‘imagemagick-path’).
