Just installed MS Office 2007 on XP running under Parallels 4.0. All of the programs in Office work fine. The problem is that I can't get .ppt files associated with the Windows version of Powerpoint. All of the files want to open with one of my Mac apps instead (Keynote or Powerpoint 2008 for mac). When I try to change the association or use "open with", the Windows version of Powerpoint doesn't even show up as an option. I can browse and find it, but when it is selected, it refuses to become an option. I've even created a brand new file with the windows version of PPT, saved it to the windows desktop, and it still believes it is to be opened by a mac app. I need to be running the windows version of PPT for presentations I give at work. Any ideas what may be going on? Thanks in advance for any suggestions.
