Error message 537 during the update of Avira Internet Security 2012

Hello,
I have downloaded Avira Internet Security 2012 to keep my system safe. Recently, I started the program and click Start Update but I received the following error message. I have attempted to solve this problem by uninstallation/reinstallation but the error still remained. I need a suggestion to resolve this weird error.
Thanks for any assistance.
