Using Keynote 6.5.2 with the presentation stored in iCloud.
I also have iCloud Drive on Win7 machine.
Pop-up says there is some conflict between versions, while I am editing the presentation on my MacBookPro (late 2013), offering me the MacBookPro version and TWO different versions on the Win7 machine.
I select the MacBookPro version and continue editing.
Then another pop-up arrives offering me only the two Win7 versions I saw before. One has to be selected to 'Keep' before the Pop-Up will vanish and I can continue working. I select the latest, press 'Keep', the pop-up vanishes and the presentation closes on my MacBookPro.
Now it WILL NOT OPEN. I have tried saving it from iCloud and trying to open it. Pop-up says 'xxxx' can't be opened.
I have tried copying the version on the Win7 machine onto a USB stick, saving it to the MacBookPro. Pop-up says 'xxxx' can't be opened.
I have tried viewing it on iCloud.com. Pop up says: This presentation can't be opened.
I am giving this presentation in 30 minutes.
Thanks Apple.
