Dear snb,
Thanks for your response.
I tried both codes, but both still opened an Office 2003 PowerPoint presentation rather than an Office 2010 PowerPoint presentation.
I don't know if it helps to show more of the code:
Of course the code fails when it gets to the part where it must open the specific file, because it has launched the PowerPoint 2003 application and cannot open a .pptx file.
I'm wondering if the problem could somehow be because I have the click-to-run version of Office 2010 installed?
