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 2…

I do recall someone on the forum stating that the 64 bit version of excel was required.

Hi @Michael_Kirschner2 Was it this topic? [image] Write To Excel Node and Excel 2016 Packages Hey Garret, I think the reason is your using 64 bit operating system but you installed office 32 bit. You need to install 64 bit office 2016. Good Luck!

Curious to see the csv export issue though… that shouldn’t be impacted by a 32 bit excel install, right?

The FilePath node gives me a file including extension, i don’t see that in your graph. [image] btw. i think Excel 64-bit is only needed when using RevitDBLink

Thank you everyone, however @Marcel_Rijsmus may be right, 64bit is not necessary, as I have checked colleagues PCs with the same set up and it works fine. @Marcel_Rijsmus But the file path is fine, its just shortened (automatically by Dynamo). I have also just done the same test in Dynamo 2.0 wit…

Jacob, I have recently re-tried and CSV now works again. But Excel does not. Another plugin within Revit i recently used tried to access excel and couldn’t due to something like Excel.Interop.Application error. Any ideas? Thank you

My guess: you need to update to a 64 bit version of excel.

Thank you. I have checked on a colleagues machine with 32bit Excel and it works no problem… Is a full reset my only option?

Not your only but likely the fastest fix. Why are you using 32 bit?

All & @jacob.small , Thank you for all your assistance. My computer recently did a Windows update to Build 17134 of Windows 10 Pro, and now it works!! Phew :grinning:
