How to Reinstall an Older iOS Version or Acrobat Reader App
Question details
User is asking how to install an older version of the Adobe Acrobat Reader app or downgrade their iPhone's iOS system to a version prior to iOS 14.
- Product
- Adobe Acrobat Reader / iOS
- Device & OS
- iOS
- Scenario
- Attempting to downgrade software or operating systems on an iPhone or iPad for compatibility or preference.
- Observed behavior
- The user needs to access older software versions but faces App Store and Apple system restrictions that block straightforward downgrades.
Before attempting to alter your operating system or app versions, identify whether your goal is to downgrade your iOS system or just install an older app, and ensure your device data is fully backed up.
Install the Last Compatible App Version
Use this method if your device runs on an older iOS and you need an older, supported version of Acrobat Reader.
Apple's App Store generally forces users to download the newest version of an application. However, if your device runs an older iOS version that doesn't support the latest app update, the App Store will allow you to download the last compatible version of the app, provided you have previously downloaded it with your Apple ID.
Open the App Store on your iPhone or iPad, tap your profile picture in the top-right corner, and select 'Purchased'.
Use the search bar in your purchase history to find Adobe Acrobat Reader.
Tap the cloud download icon next to the app. A prompt will appear stating the current version requires a newer iOS, but offering to download the last compatible version. Tap 'Download' to confirm.

Frequently Asked Questions
Can I force my iPhone to install an older app version if I am on the latest iOS?
No, the App Store does not allow users on the latest iOS to manually select and install older app versions. You will always receive the latest version that is compatible with your current operating system.
What happens to my data if I restore my iPhone to an older iOS?
If an iOS downgrade is successful (which requires the firmware to still be signed by Apple), your device will be wiped clean. Furthermore, you cannot restore an iCloud or iTunes backup made on a newer iOS version to a device running an older iOS version.
Are there lightweight alternatives to Acrobat Reader on iOS?
Yes, you can use the built-in iOS Files app for basic PDF viewing. For more advanced features without heavy system requirements, third-party apps like WPS Office offer fast, robust PDF reading and editing capabilities while remaining highly compatible with Microsoft Office and Adobe formats.
