Hi Neeraj,

This error is not specific to Blue Prism, other than it involves a .NET Framework call to an MS Office product.

As this error is generic there is no single solution. However, to aid in your investigation, we recommend you review the following external articles:

• Microsoft - c#: Excel : COM object that has been separated from its underlying RCW cannot be used
• Stackoverflow - COM object that has been separated from its underlying RCW cannot be used
• Bytes - object-has-been-separated-its-underlying-rcw
• .netFunda - COM object that has been separated from its underlying RCW cannot be used. in C#.net [Resolved]

I hope this helps.
