[SOLVED] Having trouble when saving PDF as DOCX using VBA

Having trouble when saving PDF as DOCX using VBA

The code should be simple enough, though it failed when trying to execute the SaveAs command. The error message said the file might be in use so it cannot be written.

The target directory has nothing but the PDF file itself, and it's not opened before the code was run. I have no idea what went wrong.

Sub PDFSaveAs()
    Dim AcroApp As Object, AcroAVDoc As Object, AcroPDDoc As Object, jso As Object
    
    Set AcroApp = CreateObject("AcroExch.App")
    Set AcroAVDoc = CreateObject("AcroExch.AVDoc")
    
    If AcroAVDoc.Open("C:\Users\User\Downloads\123.pdf", vbNull) = True Then
        Set AcroPDDoc = AcroAVDoc.GetPDDoc
        Set jso = AcroPDDoc.GetJSObject
        jso.SaveAs "C:\Users\User\Downloads\123.docx", "com.adobe.acrobat.docx"
    End If
    
    AcroAVDoc.Close False
    AcroApp.Exit
    
    Set jso = Nothing
    Set AcroPDDoc = Nothing
    Set AcroAVDoc = Nothing
    Set AcroApp = Nothing
End Sub

Solution

I've read through all of the Preferences in Acrobat and figured the solution myself.

Preferences > Security (Enhanced) > Uncheck Enable Protected Mode at startup

Done! No more "file might be in use" error.
