I just want to use PowerPoint activities, which UiPath.Presentations.Activities is provided. I run into issues while the workflow is trying to open PowerPoint.
I had tried to:
Repair Tool for Microsoft Office
Check the security settings of file
Start Process, it opens pptx file but the other activities of package need to use the reference which is given in the Use PowerPoint Presentation Activity.
If you want to use the powerpoint activities then you have to use " use PowerPoint activity" as the container.
May I know you are facing the same issue for all powerpoint files? If you havent tested can you create a sample ppt file and try to use it in “use PowerPoint activity” for a testing purpose.
if still error is happening, just try to update the powerpoint package
