This post might not be relevant to many unless you happen to be deploying an app that was last updated years ago.
Recently, I was tasked to deploy an app that didn’t happen for some reason.
Upon further investigation, I found the error code below:
Error Code: 751 Unsupported 32-Bit application
My first knowledge of 32-bit dated back to my very first game console: the higher the number, the better the graphic and performance of the game would be. Through this exercise, I learned that there’s also both 32-bit and 64-bit apps for iOS.
As part of troubleshooting, I found the below after performing a quick search within the VMware support site:
Error code 751 Unsupported 32-Bit application
“If the same error is listed then the application was not built to support 64-bit. iOS devices running version 11+ require 64-bit applications. You will need to contact the application developer and ask for a 64-bit version to use the application on iOS 11+ devices.”
I also found additional info in the Community Forum of the VMware support site:
- FYI: Older 32-bit iOS apps will not install on iOS 11
- 32-bit apps will not launch on iOS 11, Mac App Store transition to 64-bit from 2018
I then reviewed the version history of this particular app and sure enough, it was last updated back in May 2013. Given that iOS 11 was released on September 19, 2017, it’s doubtful that the app developer would make an effort to update this app to 64-bit at all.
As always, stay mobile!
