Any Linux users interested in a package are encouraged to contact palaeoware@gmail.com so we can assess demand. Windows A zip containing all required binaries can be downloaded from the assets above. Alternatively an installer is provided. See notes below: Note 1: the .zip archive contains all SPIERS programs (SPIERSalign, SPIERSedit, and SPIERSview). The .zip can be extracted and the programs run by double clicking the .exe files in the ./bin folder. All the required libraries have been included and are found in the ./bin folder. Note 2: The windows installer will not overwrite any pre-existing SPIERS <= v3.1.0 installations. However, it will set the default program for all SPIERS files (.spe, .spv, .sp2, .spf, and .vaxml) to to use the newly installed version. Mac Download the .zip containing the three SPIERS software packages. Open the .zip and drag-n-drop the software package to your Applications folder. This will install the software on your local machine. If you already have SPIERS installed you will be asked if you wish to replace the software. Note 1: if your Mac is set to only allow apps from the App Store and identified developers you will see a warning message stating that the programs cannot be opened. In macOS Catalina and macOS Mojave, when an app fails to install/open because it hasn't been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app. This will be required for all SPIERS applications.
