Installation failer

I tried installing sever times and no luck.  Aborted at 75% installation.  I then removed all with your AVG removal tool and then tried to re-install.  Still no luck with about 93% installed.  Error code 0xG0070643, description of:  Event exec_finished.
My operation sysem is VISTA and my MS windows are down.

Hello Tim,
We regret the inconvenience caused. To resolve the issue, we suggest you to remove AVG traces using AVG Remover Tool( http://aa-download.avg.com/filedir/util/AVG_Remover.exe ). Please restart to complete the uninstalling process. After running AVG Remover, you may need to manually uninstall any remaining AVG applications and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then install AVG Antivirus Free by clicking on http://files-download.avg.com/inst/mp/AVG_Antivirus_Free_692.exe .Thank you.

I'm sorry to say Kishore… but I'm having the same problem and I can probably discribe the problem. So I'll tell you my story. I had an alert saying "Your computer is not fully protected." So I googled the problem, and what came up on the page was Reinstall AVG. Well I uninstalled AVG, and I tried to get it back. But the whole big Error that's going through the message is basically saying "You can't install it because you had to uninstall in the first place you big fat idiot." So what do I do? I don't know, I've tried installing it over and over again no matter what. 

So… Kishore, why are you asking for the other programs that are installed into the PC when the only program we had was AVG! We were the ones being so loyal, and AVG had to kick out.
