Hmm, a bit of googling indicates you have a "Click 2 Run" version of Office 2010 (whatever that is).The link in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Office file point towards c:\program files (x86)\common files\microsoft shared\virtualization loader. I chose the CVH file, which when I go through the "set default" process, allows me to choose Microsft Office Client Virtualisation Handler to open the Powerpoint file.
Still no sign of "powerpoint.exe"!
Cheers
Neil.
I'm giving up now as I know very little about that - best I can do is this link (and links mentioned in it) about repairing...
