AVG Internet Security install stuck at 49%

Trying to install AVG Internet Security on Windows 7 Pro 64. Installation stuck at 49% and internet connection is lost. Tried to install 3 times with same results.

Hi Lathika,
 Thank you for your kind assistance. I have downloaded the offline installer and will remove old partial files tomorrow and reinstall tomorrow as it's getting a bit too late for starting the process now. If successful I will install on my other Windows 7 laptops.
 Once again, thank you for your prompt and kind assistance.
