Hi @balest01 and @yzanferrari,

that sounds like a dependency version unfortunately wasn’t configured correctly in the last update you installed. You’ll need to update the feature “KNIME File Handling Core” to version 5.2.1.v202403051007, which contains the missing method ExcelMultiTableReadConfig.setCheckSavedTableSpec(boolean).

  1. Go to “Menu” → “Install extensions”
  2. Uncheck the box “Group items by category”
  3. Find the feature “KNIME File Handling Core” (there’s a search bar above the list)
  4. Make sure that the version is (at least) 5.2.1.v202403051007 and install the feature

I hope this works for both of you, and sorry on behalf of the Dev team for the inconvenience!

Edit: You can even uninstall the “KNIME File Handling Core” feature again right afterwards to avoid warnings in future updates, the underlying code will stay updated. Features are only groupings of plugins, which contain the implementing code.
