The app does not work on your Mac OS X El Capitan after downloading from online resources such as eShareload? There are a thousands of reason in this world full in possibility. However, we would recommend some major causes and corresponding solutions solve the problems in 3 particular cases.
Fist of all, we recommend using “Unrar Sharp” application to extract the compressed (.rar or .zip) file that is downloaded from eShareload. By doing in that way, you will avoid “damaged file” after extracting.
Download free Unrar Sharp here. If you get difficult to download, look at How to download free Paid Mac Apps & Games eShareload store.
Case 1: Fail to decompress or extract, unzip the downloaded app file.
This problem is probably due to the uncompleted downloading processes. The file somehow was not downloaded completely, so please look back the article or resources associated with the downloaded apps to compare the downloaded size with the given size information. If the downloaded file size on disk is significantly less than the actual size on eShareload, you have to download the app again.
Case 2: Solve the problem of either “App can’t be opened because it is from an unidentified developer”
or “App is damaged and can’t be opened. You should eject the disk image”
On OS X Moutain Lion 10.8. to the newest – El Capitan 10.11, Apple impose a default feature that preventing mac user from installing the third party applications. That why when you launch one app downloaded from eShareload or other resources, you will face the notification “App can’t be opened because it is from an unidentified developer”. The solutions to fix:
Solution: Try to take a right mouse on the app > select Open, then a dialogue will appear. Just choose “Open“. If it still does not work, you need to modify the setting to avoid this notification:
Go to System Preferences > Security & Privacy, click on General > Choose Anywhere at Allow applications downloaded from. You now have to allow to confirm for all changed setting. Done!
Case 3: Registration failed by “The registration code that you have purchased has expired” or “the licensed has been deactivated”
There are 2 ways to solve this problem:
1, Active offline: You turn off the internet connection each time you want to use the app and active the app offline. Be noticed that when we enable internet connection, they will lock the license key.
2, Use little snitch to block the apps from internet.

This life is full of possibilities, and hopefully these 3 common cases above might help to solve your problems.
