Here is a download link for a zipped copy of the
Osiris.dll file, assuming you are having a problem extracting that file.
Did you install the
patch, if required? Re-release CD versions may already be updated (to 1.0034a; once the game can start, the version number is shown in the bottom right corner of the main menu). The DVD version is fully updated, and the CD version patch should not be installed.
If that doesn't help, there is a file verification procedure (based on the CD version) in the
Troubleshooting Tips topic, which could help identify any other missing or corrupt files.
Welcome to the forum.
