Installation stuck at 73%

Hello Sean,
I understand the inconvenience.
I request you to try installing AVG Antivirus free using offline installer which is available in this website: https://www.avg.com/download.prd-gsr-free as 32 & 64 bit version.
To determine whether your OS is a 32-bit or 64-bit, please click on this link. http://support.microsoft.com/en-us/kb/827218 .

I'm getting frustrated as I'm trying to install this program. I tried everything possible, for about 3 hours now trying to install Avast Internet security- paid on my windows 10 computer w/ an i7 processor & 32gb of RAM.

What I did:
Ran AVG Clear
ran AVG Remover
Deleted all AVG files from programdata
Removed all registries related to AVG

After doing all this, I'm stuck at 73% for 30 minutes. Under task manager, its using 0% of my processes.

Thank you for informing the status.
Yes, I see that one of our technician tried fixing the issue and escalated to senior technical team as he couldn't fix the issue.
You will get email response from senior technical team as soon as possible.
Your patience is much appreciated.
