Hi - I am running a Windows 7 machine and I had been using AVG 2014 Version. I attempted to upgrade to the AVG Zen version and now I am getting Installation failed with Error code: 0xE001F90F Description: Set mode (2).   Has anyone seen this before - Any thoughts on how to get round this ?

Problem solved - Thanks for the quick resposnse.  The avg_remover_stf_x64_2015_5501.exe cleaned things out so the new version would load.
