I don't understand what you're doing here.
I must admit that me neither! Sorry if my explanations are confusing.
In the .iso file, there is:
- Carmen Sandiego installer
- Desktop folder \ empty
- Multimedia extension folder
- Additional Power Mac Extension folder
- Extensions for all Macintoshes folder
- QuickTime 2.1
- Sound Manager
- System 7.1.x or 7.0 Users
- Miscellaneaous
- QuickTime Musical Instruments
- Sound
- Vintage Beep
- Readme
- Text about how to install QuickTime, QuickTime PowerPlug and QuickTime Musical Instrument. I followed the instructions to drag & drop the icons in the System Folder, then Extension folder
- Text about how to install Sound Manager and Sound control panel, I followed the instructions
- Carmen Sandiego Readme about troubleshooting and performances
Thank you for suggesting QuikTime 2.5, I just successfully installed it, deleted all the game files, and installed them again. And the error no longer happened!
BUT! Now I am confronted to a new error: when I click the icon to launch the game, a pop up tells me to "Insert the CD in the CD ROM drive then click OK". Thing is I don't have the CD

I can only guess it's about mounting the image, topics (
here,
here or
here) I could find here were about SheepShaver or Power PC.
Do you know what I should do next?
Thank you very much in advance!
