Here is a download link for a zipped copy of the Osiris.dll

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.
