I have been trying to answer this question in the Mindjet Forum, I have spent a bit of time working it out and I think I have cracked it.
In summary: You must use the PowerPoint Viewer and hold down the Ctrl key when clicking the link!
My research suggests you cannot start a show at a specific slide using PowerPoint but you can with the PowerPoint Viewer. See this write up about command line switches from Microsoft.
MindManager has to mimic this command line which when entered via the Windows Start button opens the slide show at the sixth slide ( /n6 ) e.g.:
C:\Program Files (x86)\Microsoft Office\Office14\PPTVIEW.EXE /n6 “G:\Andrew\Documents\Auctions in a Day\Alresford Auction Presentation.ppt”
Initially I could not get this to work in MindManager by either using the complete line for the hyperlink or splitting between:
Link to: C:\Program Files (x86)\Microsoft Office\Office14\PPTVIEW.EXE
and Options > Argument: /n6 “G:\Andrew\Documents\Auctions in a Day\Alresford Auction Presentation.ppt”
BUT it does work in MindManager 6 with PowerPoint Viewer 2003 running on XP SP3!
Eureka! It does work with MindManager 9, if you hold the ctrl key (or disable the inbuilt browser pane) when clicking the link.
I also tried making the PowerPoint Viewer the default .ppt program, and then entering this:
Link to: G:\Andrew\Documents\Auctions in a Day\Alresford Auction Presentation.ppt
and Options > Argument: /n6
Hold the ctrl key down when clicking the link and it works. Otherwise the slide editor opens in the in built browser pane.
Alternative Solution: Create a batch file “Alresford Auction Presentation Slide 6.bat” with the full PowerPoint Viewer command and use this as the hyperlink.
Can you improve on this?
