      3D PDF creation fails with "Typelib export: Type library is not registered" with Inventor 2025

      Issue

      When using Inventor 2025 the 3D PDF job runs into the error "Typelib export: Type library is not registered. (Exception from HRESULT: 0x80131165)"

      Cause

      This issue is related to the change to .NET 8 in Inventor 2025.

      Solution

      Open the file "3DPDF.psm1" located at "C:\ProgramData\coolOrange\powerJobs\Modules" with any editor. Search for the following line of code:

      $3DPdfConverter.Publish($Document, $options)

      Replace it with the following:

      [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.VisualBasic")
      [Microsoft.VisualBasic.CompilerServices.NewLateBinding]::LateCall($3DPdfConverter, $null, "Publish",@($Document, $options), $null, $null, $null, $false)
