Fatal Error after deleting excel file with Post Deployment Action Update RRS feed

  • Question

  • I have an excel customization with a post deployment action following instructions at

     I'm trying to copy the excel file with the customisation to the end user's computer. The file is set to check for updates each time it opens. It works fine for install and uninstall. The update code runs OK and replaces the existing file with the updated file but after the code runs I get a fatal com error. I can't figure out how to handle the fatal error so the end user doesn't see it as it happens after the post deployment action.

    Using VS 2010 & Excel 2007.



     Select Case args.InstallationStatus

                    Case AddInInstallationStatus.InitialInstall, AddInInstallationStatus.Update

                            'check if Excel is open
                            xlApp = Marshal.GetActiveObject("Excel.Application")
                        Catch ex As Exception
                            xlApp = Nothing
                        End Try
                        If Not xlApp Is Nothing Then
                                'Excel is open so close file if it is open before trying to delete it
                            Catch ex As Exception
                                Exit Try
                            End Try
                        End If

                        If System.IO.Directory.Exists(destPath) Then
                            'If destFile exists delete it before trying to copy in the new file
                            If System.IO.File.Exists(destFile) Then
                            End If
                            'Folder doesn't exist yet so create it
                        End If

                        System.IO.File.Copy(sourceFile, destFile)

                        If ServerDocument.IsCustomized(destFile) Then
                        End If
                        ServerDocument.AddCustomization(destFile, deploymentManifestUri)

                        Exit Select

                    Case AddInInstallationStatus.Uninstall

                        If System.IO.File.Exists(destFile) Then
                        End If
                        Exit Select

                End Select

  • Windows 7 enterprise 64, Office 2007. I'm guessing its because I've deleted the file the update code is running on. Error message,

  • In this thread, the initial poster resolved his issue by installing SP. You can also try this.

    with regards, Yuri

  • Thanks for the reply Yuri. I have Office SP3 installed and ran updates the other day so I don't think that is the problem.

  • I've also tried it with Excel 2010 and VS 2012 and get the same error.
