Unable to Write to Excel

[awilliams]

@Mike_Engel1 Do you have Microsoft Office 365 Business by chance? I recently had this problem after Office 365 updated, and @Kulkul recommended uninstalling and reinstalling Microsoft Office 365 Business - after this my Excel nodes in Dynamo worked again. This thread here also offers some other solutions:

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
