App Store prompts "Download XX" Failed to use purchased page try again

1. I was prompted to re-enter the pages of the purchase page to download software, the results found in the purchased page is being installed, so do not know how to operate, below we look down.

2. As shown in the following illustration, we now open the "application" below the Finder and we will see that we have just downloaded the failed software.

3. Now we temporarily exit the App store to shut down, then we double-click the download failed software, and then you will see is downloading, and is the normal download Oh.

4. So we just wait for a while to download the finished oh very simple.
