Excel - Operation failed

Hi, I have been struggling to fix an error with the Excel and CSV Import and Export nodes. When using them, I receive the following error. I have search the forum and reinstalled Excel, upgraded Excel, Reinstalled Dynamo, and Reinstalled Revit, with no improvement I am currently running: Revit 2017.2 Dynamo 1.3.2 Excel 2013 (32bit) Note I have installed Excel 2016 and this didnt help. I have also deleted the 1.8 file in the registry. Any ideas would be greatly appreciated! [image]

Excel.ReadFromFile operation failed

@htlcnn, sometimes something goes wrong with Excel. Have a look at the known issues here: Excel nodes can be rendered non-functional by bad registry data. To correct this: Go to Start–> Run --> regedit. Browse to HKEY_CLASSES_ROOT–>TypeLib–>{00020813-0000-0000-C000-000000000046}. Delete the 1.8 key. We recommend using Excel 2013 or higher. Excel 2010 works in most cases, but 2007 does not. You can also dive into this thread, maybe, it’ll help you: Excel Nodes Fail Dynamo 1.1.0
