I have had this for a few weeks now:
When I double-click a ppt or pptx file from Windows Explorer, I get the following error message:
SlideShowWindow (unknown member) : Invalid request.
Automation rights are not granted." + OK button.
I then click OK, PowerPoint and Presenter work normally, but if I open another file in the same way, PowerPoint crashes and wants me to disable Presenter.
HOWEVER, if I open PowerPoint 1st, then open my ppt or pptx file using menu FILE /OPEN, it does not crash.
I have Presenter 7.0.7
Internet Explorer v.8.0
Windows 7 Service Pack 1 - 64 bit
We have already deinstalled and reinstalled Office 2010 and Presenter twice, and downgraded IE from v.9 to v8... as I found something on the Internet about this.
I have gone through this forum, found another thread on same topic, but it did not solve my issue.
