I have tried installing C2000WARE 2.00.00.03 on a MacBook running macOS Catalina without success.
First, macOS stopped me from executing the installer, warning it came from an unknown source. Going to Security & Privacy settings and overriding this warning solved this part.
However, it then apparently did nothing when I tried running C2000Ware_2_00_00_03_setup. Trying to run it on Terminal returned an error:
LSOpenURLsWithRole() failed with error -10810 for the file /Users/andrerc/C2000Ware_2_00_00_03_setup.app.
I also tried running C2000Ware_2_00_00_03_setup.app/Contents/MacOS/installbuilder.sh, which returned the following error:
./C2000Ware_2_00_00_03_setup.app/Contents/MacOS/installbuilder.sh: line 18: ./C2000Ware_2_00_00_03_setup.app/Contents/MacOS/osx-intel: Bad CPU type in executable
Additionally, I tried running xattr -r -d com.apple.quarantine C2000Ware_2_00_00_03_setup.app, but that didn't change any of the reported outcomes.
