  • Thanks to a French Siril user (Colmic) there are now two possible methods to install Siril. The first one is based upon an installer that will install Siril and also some very useful scripts in the right place. If you did previously manually installed the 0.9.9 version, some conflicts may occur. Please remove old Siril application and also the siril directory located in %AppData%. It is important to read all messages during installation: download automatic installation.
  • As usual we provide an archive with all the needed files in it. We recommend you create a shortcut for the executable at any convenient place. The executable is in the subdirectory bin and is named siril.exe: download archive.
