I'd be happy to help you install HDRsoft Photomatix Pro 7.1 Beta 7 on your iOS device.

Before we begin, please note that since you're using an iOS device, we'll need to download and install the app from the App Store.

3. Select the result that says 'Photomatix Pro 7.1 Beta 7' from HDRsoft.

4. Tap the 'Get' button next to the app icon.

5. If prompted, sign in with your Apple ID or create a new one if you don't have an existing account.

6. Wait for the download and installation process to complete. This may take a few minutes depending on your internet connection speed.

7. Once installed, tap the 'Open' button to launch Photomatix Pro 7.1 Beta 7.

That's it! You should now be able to use Photomatix Pro 7.1 Beta 7 on your iOS device.
