SketchBook iOS: This app is not compatible with your device.

I am back, sort of.  I am currently on the SketchBook QA team and we are getting a lot of tickets on this topic so I wanted to share this with the community. 


If you get this error when trying to update SketchBook from 3.7.4 to 4.0.4 on an iOS device:  This app is not compatible with your device. 

This app is not compatible with your device 2

DO NOT DELETE IT FROM YOUR iPad OR iPhone!  If you delete it, you will not be able to re-download it from the AppStore because the version on our AppStore is 64 bit.   Believe it or not, there are iOS devices are 32 bit or 64 bit and the easiest way to tell is by processor type.  You just need to know this one rule:

Any iOS device with an A7 Processor or higher  is 64 bit.

We have a long list of compatible hardware and it is noted on the SketchBook iOS product page:

Compatibility: Requires iOS 9.1 or later. Compatible with iPad Air, iPad Air Wi-Fi + Cellular, iPad mini 2, iPad mini 2 Wi-Fi + Cellular, iPad Air 2, iPad Air 2 Wi-Fi + Cellular, iPad mini 3, iPad mini 3 Wi-Fi + Cellular, iPad mini 4, iPad mini 4 Wi-Fi + Cellular, 12.9-inch iPad Pro, 12.9-inch iPad Pro Wi-Fi + Cellular, 9.7-inch iPad Pro, 9.7-inch iPad Pro Wi-Fi + Cellular, iPad Wi-Fi (5th generation), and iPad Wi-Fi + Cellular (5th generation).

For more information on 64 bit support on iOS from Apple,  go here:

If you need to backup your older version of SketchBook, you can back it up via the iCloud.

If you decide to upgrade your iPad that has A7 Processor or higher,  you are still entitled to the upgrade to SketchBook 4.0 for free.  You just need to download from the AppStore and restore it.

I have also talked about 32 and 64 bit computing back in 2011 from this older Up and Ready Blog post:

Epilogue [June 13, 2017]

We have fixed the back end systems from Apple to resolve this issue.  You can now download a 32 bit app if you are on a 32 bit device.  Thanks to Andy Chang and the Development team for resolving this issue!


A Celebration of Life....

Giancarlo-moloWith great sadness, I have been informed that one of the founding members of this blog and a geographically distant friend, Giancarlo Molo, has passed away.

He has been a part of Autodesk for over 20 years and my first meeting with him was in 2011, when we went to Manchester, NH for Citrix XenApp 6.0 training.  Some of us came down from Toronto to the Boston and we waited for him at the airport to pick him up from Switzerland.  I recall holding a sign with his name on it so I basically looked like a limousine driver.

My last (9/15/2015) online chat with him is below:


Carpe diem.  There is no time like the present and there's no present like the time. If you have any fond memories of Giancarlo, please feel free to comment in this post.

Where is Fusion 2014 ?

Inventor Fusion is not one of the products listed when you try to install from the 2014 install media.

In its actual form, it has been discontinued and its replacement is Fusion 360 on our cloud platform.

Good news!

We released an updated version for 2014 release called Inventor Fusion 2013 R1.

It is available from the following address and it is free to all customers.


A note for users running Fusion 2013, please check out this known issue:

Thank you to Kevin Schneider for clarifying.

Simulation CFD 360 2013 FAQs

Here are some tips from the Autodesk Simulation CFD team for 360 users:

1)      Contract Manager needs to add the user to their contract and make that user the Software Coordinator for the 360 Serial Number.

2)     Contract Manager needs to make sure that the user has Simulation 360 access under Subscription Center.

3)      User needs to log into and type in the serial number to ‘enable their subscription’.

Autodesk: Moving to the some point in the future...

From one of our fellow bloggers, Kean Walmsley, and a very interesting article on the 'cloud':

This is a topic I’ve been meaning to cover for some time. It concerns a transition we’re seeing overall in the software industry, and is certainly one that the ADN team broached in depth during the last two DevDays tours.

I don’t think anyone is in real doubt, at this stage, that software is increasingly being delivered “as a service”, rather than via locally-installed desktop applications. Some readers may understandably be skeptical about the near-term likelihood of powerful design tools working in the cloud… I personally believe it’s an inevitable shift (whether we’re talking about a timeframe of 2 years or 10 is the real the question, in my mind), but I won’t try to convince anyone of the correctness of these opinions....

Autodesk Suites: Using Environments tab (Optimization) in Inventor Professional (PDS) will request activation

You have installed Autodesk Product Design Suite Ultimate and  you have successfully activated the product.


When run Autodesk Inventor Professional and you click on the "Environments tab", it will try to re-activate your software.



NOTE:  The Activation request will be for Autodesk Product Design Suite Premium.



To resolve this issue, you will need to:

1.  Set following registry key : 

  • HKEY_CURRENT_USER\Software\Autodesk\Inventor\Current Version\OptimizationUpdateNotified to 1

2.  Download Inventor Optimization manually from Subscription Center.

  • Install Optimization first THEN go to the Environment tab to run Optimization.
  • When you open Optimization from Inventor, you will be prompted for your Subscription center username and password.

Thanks to Bob Vander Donck, the Inventor Team and Byron Morales for this workaround.


This issue should be solved in Inventor 2012 SP1.

If you are a PrDS user, the Optimization patch will be downloaded automatically once you launch Inventor, the downloading location is in the folder " %Temp%", the time of the downloading depends on your network speed, when the downloading is finished a automatic prompt message dialog will be shown in Inventor, and Optimization patch is named "centaurupdate.exe" will be in folder " %Temp%".
