Hi @andcol
Could you pleas let us know what format of the workbook? If it is .xlm, I suggest you save it as .xlsm.
Please make sure no object or range named Print_area, if there is any existed one, you need to rename it.
Besides, if that object or range is used in the macro, please also change the code to reflect the new name.
Here are 2 articles you may have a look.
Why am I seeing the Name Conflict dialog box in Excel
