You basically have a mismatch of versions between your viewer app and folio. Your folio has been made with a software version that's newer than what your app can read.

I just fell into the same pitfall.

Your options are to create a new viewer app using the latest viewer builder and submit it to Apple for approval.

Or uninstall your folio builder tools and re-install your previous version, then recreate the folio.

Do the uninstall Folio Producer tools again following the steps but this time uninstall the Folio Builder as well. There should be an uninstaller file for that in the same directory.

Then download the previous version of the folio panel from here...

Install the producer tools first, then the folio panel, then launch Indesign and deleet all the artcles from your folio before adding them back in.

Unfortunately I don't have any more advise for you. I followed those steps and was able to recreate my folio.

I have both updated  Content Viewer and  Folio Builder, but still am not seeing my updated folios in the Viewer. Any advice? This was all working smoothly last week....

Thank you Bob, that worked perfectly. I should've though of that!

I'm experiencing the "please update your ap from the app store" message too.

This has happened before, and it's beginning to become a tad annoying.

Is there a clear and simple way to solve this please? I have to publish my latest magazine edition today. Everything was going smoothly until I tried to download the app on my ipad. once again everything has come to a grinding halt, and looking back over all the messages here, it looks like there are several compliacted, convulted "solutions". I don't want to choose the wrong one.

I am using the latest Folio updates, as I was prompted to do in the InDesign panel. No choice was given to NOT update. Now I've updated, I've got the error.

So, to clarify before I do anything, I can use the v17 FP tools, with the new Viewer Builder?

I can't recreate the app because I have to have the magazine available today.

Once I have v17 FP tools and the v19 FB installed, do I have to go back into indesign and do anything to my files, or should everything magically sort itself ouot in the Folio Producer: Organiser window on the DPS site?

Hang on, I'm not using the Viewer Builder, that's to submit to the app store. I'm just trying to publish the latest edition of an app that already exists. It should be simple, but I'm pretty sure this "update your app" issue has happened before, to many people.

And in the app on the iPad, I get the same "please update your app" message.

I've changed the file name, retested a folio, and still get the "update your app" message.

I will start it all from the update stage again, I've already done this twice. Im also 13 minutes away from missing my deadline.

I have another publication due for release on the 9 February. This publication is for a worldwide mining conference in Canada. We are the media sponsor. I'm guessing that I am goign to miss that one as well, as the same issue will occur.

Thanks Bob. It's just upsetting, in that I've done my work, finished

everything on time, only to be let down by technology at the end, and also,

the advertising clients don't make life very easy, which in turn means the

sales people are standing over me. I've lost a day n the other publication

due next week, so I've just lost my weekend. It's also embarrassing because

I can't work out the problem, so I can't fix it.

Thanks for helping me today Bob.

I just tried the whole process from scratch and was unsuccessful. I'll be in

over the weekend to catch up on my other work, so I'll maybe try everything

again, again.

Yes, sorry this is so difficult. There are plans to simplify this process.

Thank you for the link Bob. I am no closer to a solution to the actual problem though.
