https://community.blueprism.com/t5/Product-Forum/Open-Workbook-error/m-p/84513#M35641 Hi, I am facing a problem with opening Excel. I did a small flow using MS Excel VBO. Workflow consists of 3 objects: 1. Open Instance (Input - whole path of file, Output - handle) 2. Open Workbook (Input - handle, File name whole path of file) -> I am getting error: "Internal : Could not execute code stage because exception thrown by code stage: Exception has been thrown by the target of an invocation." 3. Show (handle) I tried this solution on another PC and it works properly without error message. Could you advise me what is causing this problem and what is the solution?

I tried with this also but it didn't work. The problem actually is in VBO code object named ""Open Workbook"". Maybe some dll is missing?

Dim wb as Object = GetInstance(handle).Workbooks.Open(filename) name = wb.Name wb.Activate() Fri, 13 Oct 2017 11:42:00 GMT https://community.blueprism.com/t5/Product-Forum/Open-Workbook-error/m-p/84516#M35644 ekinsuugur 2017-10-13T11:42:00Z
