Hi Vitamin. No difference after deleting .wine and reinstalling. The Windows error msg is a small window with 'Setup Error' in the title bar. There's a big red X in the pane and this exact message: 'Setup cannot find the necessary files.' Below that is an 'OK' button which closes the window. No option to learn which files are needed. (This is why I migrated to Linux years ago. Windows is built to be unhelpful. Now if only sqlite3 had FMP's friendliness...)
