"Permission denied" when installing XModules via terminal

How do I bypass “Permission denied” when installing XModules via terminal? Im getting this error when using with bash
:

"…ui.vision-xmodules-mac-v201908/1install.sh

File ‘kantu-xy-host’ is not executable or found

File ‘kantu-cv-host’ is not executable or found

File ‘kantu-file-access-host’ is not executable or found

It seems the extracted files are NOT executable. You need to make them executable with chmod +x."

Thank you for your help!

On macOS it is sh 1install.sh (so “sh” not “bash”). Does this solve it?

Where do i enter that in? Together with folder? Sorry, new to terminal commands…
