Re: Configuration Error: 5(Renamed)

Hi Bob. 

I have updated to High Sierra and I'm trying to reinstall Illustrator from my Time Machine backup and I keep getting the message "Configuration Error: 5" I have the original software CD and it was registered with Adobe at the time I purchased it and I have a link to the CS5 Design Premium files I bought but I don't want to open them because I don't want to overwrite my entire existing CS5 Design Premium softwares, especially Photoshop. Can you offer any help please?
