Hi,
How to I get IE9 to automatically open the .PPTX in Powerpoint 2010 instead of showing the save/open dialogue box?
I have created a key in HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046} with PowerPoint.SlideShowMacroEnabled.12 set to 0 but this doesn't work.I have added the intranet as a trusted location etc.
Any ideas?
many thanks
