system.runtime.interopservices.comexception UiPath I am getting this Exception So that inbetween Some Word Files are Converting but some file are not Converted

Hi @Gopikrishna_S

The System.Runtime.InteropServices.COMException error in UiPath typically indicates an issue when working with COM objects, such as Microsoft Word in your case. This error can occur for various reasons, such as problems with file access, file corruption, or issues with the COM interop.

Is their any Solution to overcome it

Include those possible activities that can fail within a RETRY SCOPE activity where inside the ACTION Block first place a KILL PROCESS with ProcessName as “WINWORD” and then place the activity that you found as failing


Workflows\WordFile_to_PDF_File_Conversion.xaml - Invoke Workflow File: Expression Activity type ‘VisualBasicValue`1’ requires compilation in order to run. Please ensure that the workflow has been compiled. Getting this error while placing Kill Process activity I have entered Process Name section I have entered “WINWORD” String

Thank you Palaniyappan for your suggestion
