AVG Security Pro installation stops at 83%

I just purchased a one year unlimited devices license for Windows AVG Protection. I am trying to upgrade my revious license in ZEN. The install stops at 83% with the general error code 0xC0070781. I've tried the download and update several times with the same result.
