  • Installation instructions (SpiceOpus_Installation.pdf) Read this file before you install SpiceOpus.
    Make sure you set the OPUSHOME environmental variable for versions prior to 2.32.
  • For version 2.32 and above the environmental variable is set by the installer.
  • Under Windows 10 the new variable is effective only after reboot or if you go to
    'Control panel/System/Advanced system settings/Environmental variables'
    and confirm the last two dialogs with OK. We know this is weird. Ideas and solutions are welcome. We are building the installer with Wix 3.11.
  • Make sure you uninstall SpiceOpus version 2.31 or earlier before you install version 2.32.
