Software Center packages will often uninstall the old version to reinstall the new one. If upon reinstall the package finds DLL files, it renames rather than deleting them. See screenshot below for example.
- Uninstall Studio.
- Remove Winshuttle folders from C:\Program files and C:\users\<username>\appdata.
- Reinstall from Software Center.
