The error you’re encountering usually means that the installer is trying to write a file that is currently being used by another process. We can try two possible solutions to resolve this:
Open Task Manager, look for any processes with “Roon” in the name, and close them. Then try running the installer again.
Go to Control Panel → Uninstall a program, find all applications related to Roon, and uninstall them.
After completing these steps, try running the installation again. If you encounter any further issues, feel free to update us here.
Laptop cleaned with cleaner, . roon removed from download. restarted. looked in task manager and found nothing of roon. seems logical to me if you can’t install
Would you kindly clarify whether you currently have any antivirus software running? If so, could you please try temporarily disabling it to see if it affects the issue?
