AVG gave me an update one click option recently… I used this only for install to fail and half an installation complete. Had to revert to old version which then did not want to load. Tried the AVG removal tool and clean install from latest download version but keep getting 'Error code: 0xE0018D32
Description: Event exec_finished' after AVG downloads during the install process.

Any ideas what is wrong?

Please visit this webpage http://www.avg.com/us-en/download.prd-isc to download the offline installation file.
Run the downloaded file to start the installation process.
Follow the instructions on your screen. When prompted, enter your AVG license number.
The license number is sent automatically to your e-mail once purchased.
Complete the installation and restart your computer.
Please, feel free to let us know if you require any further assistance. Thank you.
