Hemisfer is very easy to install: double-click on the downloaded MSI intallation file and follow the instructions there. A shortcut will be placed in the start menu. You need administrator rights to use this automatic installation. Since the project is not signed, a warning will appear and you'll have to confirm that you want to install the software.
If you downloaded instead the ZIP file for a manual installation, it is not complicated either: uncompress all files into a folder of your choice. You can then make a shortcut of Hemisfer.exe in your start menu or on your desktop. This method should also work if you cannot obtain administrator privileges.
Hemisfer is provided with a few external language files. You can therefore choose another language at any time without having to reinstall anything, not even to leave the software. It is also possible to write a new language file, taking those provided as examples. It would be nice to share it if you write such a file: please e-mail it to the author. Language files released later than the corresponding software version will be posted on the web site.
After installation, the free downloadable software is limited to an image analysis within a radius of 500 pixels. This limitation is removed upon registration.
