Program Installation

Weasel, ACluE and the free software are java programs and require java version 1.7 or later that will be found on (or can be installed on) most recent computers (e.g. Mac OS X 10.7.3 (Lion) or better. Installation is manual but is not too tricky if you follow the tips below:

Windows PC

  • To see which java version (if any) is installed, launch the command window and type "java -version".
  • If your computer does not have Java, download it from Java.com and install it.
  • Other than for the free software, right-click the downloaded .zip package and select "Extract All..." to extract the program folder. 
  • The intact folder typically will be dragged to C:\Program Files or C:\Program Files (x86) but it will function wherever it is stored. 
  • Launch the program by double-clicking the .cmd command file (Weasel.cmd or ACluE.cmd) or, for the free software, double-click the .jar file.
  • Launch enhancements for advanced users and .cmd file editing advice are in the enclosed README.txt

Unix varieties or other computers

  • If your computer does not have Java, download it from Java.com and install it. 
  • After extracting the program folder, the program can be launched by double-clicking the .jar archive however, other than for the free software, it is preferable to use a launch command that sets the initial memory heap allocation.  See the enclosed Weasel.sh or ACluE.sh shell file and README.txt for more information.  

Macintosh

Sorry Mac users! Apple are making us jump through even more hoops for installation. For recent OS X versions, program installation requires administrator privileges to appease the OS X Gatekeeper and avoid the erroneous "...app is damaged..." message. 
  • To see which java version (if any) is installed, launch the utility Terminal.app and type "java -version".
  • If your mac does not have Java, download it from Java.com and install it.
  • Other than for the free software, if the downloaded package is a .zip, double-click  to extract the program folder containing the .app application. For Weasel, packaged as .dmg, open and drag the folder to your location of choice.
  • The intact folder may be placed in "Applications" but it will function wherever it is stored. 
  • For computers running MacOS Sierra (10.12) or up to Big Sur (11.2), bring up a Terminal window and type (red section):

  • My-iMac: myAdminAccount$ sudo spctl --master-disable
    Password: [enter your administrator password]


  • In all MacOS systems, launch System Preferences, select Security & Privacy, unlock the controls and set "Allow apps downloaded from:" to "Anywhere". 



  • Right click on the app (Weasel.app, ACluE.app or the free software .jar file), select "Open" and confirm the "Open" request.
  • The program will launch and can be run from then on just by double-clicking.
  • Return your Security & Privacy settings to their original state.
  • If your computer is running MacOS Sierra (10.12) or later, bring up the Terminal window and restore the original system state by typing (red):

  • My-iMac: myAdminAccount$ sudo spctl --master-enable
    Password: [enter your administrator password]

  • Launch enhancements for advanced users are in the enclosed README.txt
