Remember the developer “name” in the popup after you click the app, then click Cancel.

Click the app icon created on your home screen.

In the meantime, we recommend downloading apps from alternative app installers.

The “ Unavailable” button will be gone and you will again see the “ GET” button.

The solution is waiting for 24- 48 hours before the AppValley team can acquire new certificates.

If you are not seeing the “ GET” option beside every app and the download button appears “ Unavailable” as shown in the image above, this means that the developer profile certificate of AppValley has been revoked by Apple.

If AppValley is not working for you, then try an alternative app installer on the linked page.

Select the AppValley profile and tap on Install.

Now go to the Settings app and go to Profile Downloaded.

You need to give permission for the profile to download, tap the Allow option on the popup that appears.

Tap on the Download button above to get the AppValley configuration profile.

My computer operating system is too old to run Graphical Analysis, Spectral Analysis, or Instrumental Analysis. You will not be able to get Graphical Analysis from the main app store entry. Launch the App Store app, and view the list of already-purchased apps. Check that the device is logged in to the App store with the same Apple ID that has already been used to acquire Graphical Analysis GW, and log in as needed. Now take the iOS device with the older version of iOS, such as iOS 9.

If you acquired Graphical Analysis in the past, you need do nothing but the next steps.

You don’t need to stay logged in after this one-time download. You must have obtained Graphical Analysis GW at some point if it has never been downloaded under a given Apple ID, you will have to use an iOS 11 device, log in under the desired Apple ID, and get the app.

You can still get a version of Graphical Analysis compatible with iOS 9 or 10 from the list of purchased apps (but not from the main App Store entry for the application–you must go to your list of purchased apps). You cannot download an older version of the app from main App Store entry.įor example, Graphical Analysis GW is marked in the App Store as being compatible with iOS 11 and newer. Once you have done this on one device, you can go to your list of purchased apps and see the app download it from there. To do this, you must have already purchased or downloaded the app under your Apple ID. It is possible to download an older version of iOS apps from the App Store.
