Error 0xe001f921

I was downloading AVG zen free. And my laptop shut down in the middle of installation.  There is no shortcut for AVG on my desktop, and nothing showing that it is downloading. I tried to run the installation again and I get the message Installation already in progress error code 0xe001f921. I tried to look in my files to uninstall anything downloaded by AVG but there is nothing there.  Is there anyway to install this again?  I was able to install it on my other laptop with no problems.
