Microsoft.Office.Interop.PowerPoint not working in build (win standalone)

Hi,
I'm trying to get Microsoft.Office.Interop.PowerPoint working in Unity 2017.4.8 (.NET 4.5). It works fine in the Editor but when I do a standalone build the app crashes and I get the following error:

Code (CSharp):

1. System.Runtime.InteropServices.COMException (0x80080005)

Any help would be greatly appreciated!

 

As far as I know using office libraries requires Office to be installed on target device, are you aware of that?

 

Yes, office is installed. Otherwise it would not work in the editor either, no?

 

What library are you using to interop with PowerPoint?

Can you show us the offending code?

Is this taking from the output_log.txt file? Can you show the entire thing?

Have you built your game with the 'Development' option flagged and then connected it to the debugger and stepped through the code that way?

Here is the basic setup:
Four dlls:
Microsoft.Office.Interop.PowerPoint.dll (from nuget)
Microsoft.Vbe.Interop.dll (from C:\Windows\assembly)
Office.dll (from C:\Windows\assembly)
stdole.dll (also from C:\Windows\assembly)

Code for testing:

Code (CSharp):

1. using System;
2. using System.IO;
3. using Microsoft.Office.Interop.PowerPoint;
4. using UnityEngine;
5. using Microsoft.Office.Core;
6.  
7. public class OpenPowerpoint : MonoBehaviour
8. {
9.     public string FilePath;
10.     private Presentation Pres;
11.  
12.     // Use this for initialization
13.     void Start ()
14.     {
15.         var App = new ApplicationClass();
16.  
17.         var path = Path.Combine(UnityEngine.Application.streamingAssetsPath, FilePath);
18.         Pres = App.Presentations.Open(path, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoTrue);
19.  
20.         App.ActivePresentation.SlideShowSettings.Run();
21.     }
22.  
23.     private void Update()
24.     {
25.         if (Input.GetKeyDown(KeyCode.RightArrow))
26.         {
27.             Pres.SlideShowWindow.View.Next();
28.         }
29.  
30.         if (Input.GetKeyDown(KeyCode.LeftArrow))
31.         {
32.             Pres.SlideShowWindow.View.Previous();
33.         }
34.     }
35. }

Works in editor but crashes at

var App = new ApplicationClass();

Yes the error is from the output_log.txt.
I tried connecting the debugger, but there is not much to step through.

 

Yeah I found that too but they seem to have a different error and never found a solution

 

I am running into something similar. Did you ever figure out a solution for this?

 

I ended up writing a separate .net console application and starting it via Process(). Communication was done using sockets (UDP).

 

hi @zyzyx may i know if u are able to extract powerpoint slides from the editor

 

did u find anything
