I tried using Excel.ReadFromFile node but it failed. I’ve read some topics on this forum but haven’t found any solutions. I’m running Revit 2018.1, Dynamo 1.3.1.1736, windows 7 x64, Office 2010. I’ve tried xls, xlsx files at many locations, all granted Editing permission to Every One (I guess I do…

Hi @awilliams Could you let us know the below versions your currently using. Windows Revit Dynamo Excel

Hi @Kulkul - sorry, I should have thought to include before. I’m currently using the following: Windows 10 Pro Revit 2016 Dynamo 1.3.1.1736 Excel 2016

@awilliams Install this application https://www.auslogics.com/en/software/registry-cleaner/ It will automatically remove duplicate keys and keep the ones needed. Its a free tool.

Thanks @Kulkul - I used the tool and restarted my computer, reopened Revit & Dynamo, and the Excel nodes still fail… I suppose I’ll have to resort to reading/writing with CSV from now on :persevere:

What’s in the registry now relative to excel? You may want to reinstall dynamo, and attempt to read and write excel nodes without any custom nodes installed as another “troubleshoot the system” effort.

@jacob.small this is what is in the registry now: [registry 2] I tried troubleshooting by reinstalling Dynamo without custom nodes/packages and the Excel nodes still aren’t working. Could you or someone share what their registry has in it so I can compare?

My IT department has me locked out of that, but I can ask around. Consider posting the issue to the Github page to get some more direct developer attention.

@awilliams , i only have the 1.9 key as well and i dont have those issues. What you could try is backup your register and delete the 1.9 key? If you can delete the 1.8 key then it shouldnt be a problem for the 1.9 key either, but always make a back up.

@awilliams Why not just uninstall excel and re-install it.

Finally solved the Excel nodes working by uninstalling & reinstalling Microsoft Office 365 Business. Thanks to @Kulkul !
