Oh sorry.... I deleted it because I saw after I'd posted that you'd been around here a while, so I figured these two solutions I guessed were likely a little too obvious to be the cause of your issue.
Anyways, I have never had this happen yet, so I'll let someone else suggest more. I hope you figure it out.
One thing I'd wonder though, is there any commonality between the ones that are missing (unlike ones that are showing up)... such as install folder, or perhaps 32 bit vs 64?
