Installation Error Message - 0xE001D029

Trying to install AVG Internet Security and transfer my licence, every time I try I get the above error message. Any suggestions as to what this could mean?

Have read that and followed it, that's when I get the error message and can't get any further. Have tried to talk to Technical Support but have been waiting for an on-line chat to start for an hour!
