Step 2: On that page locate 'Flash Player for Android 4.0 archives' if you have a lower Android version they also have a 'Flash Player for Android 2.x and 3.x archives'. All of these options will be located near the bottom of the page.
Step 3: Download which ever one you want. If you want the latest version of Adobe Flash Player then the latest will be at the top of the downloads list for your android.
Step 4: Go into settings. Tap on security. Then find 'Unknown Sources' on the page. You need to allow it in order to install it.
Step 5: Once the download is done click on the install button. This should take a few moments. If you have something like AVG or antivirus stuff it will come up with 'Package Installer' or 'Scan for viruses'. You need to press Package Installer. Don't worry as there is no viruses on the files.
Step 6: Once all this is done you should repeat step 4 but this time disallow it by pressing it for safety reasons. e.g. viruses.
I hope this all goes well and I hope you enjoy my app
