AVG appears to keep breaking the "Microsoft Visual C++" installations. I noticed windows kept reinstalling a succesfully installed updated for C++. I went into "Control Panel\Programs\Programs and Features" found all my C++ installations, I had Redistributables for 2010, 2012 and 2013 in x86 and x64 installations. I went to each one of them and hit "Change" then "Repair" on each one of them then rebooted and now everything with AVG loads, except the firewall. I still can't get the AVG Firewall to install and when I try to it gives me an error code then breaks parts of AVG and I have to rerepair the C++ installations and reboot.
My question is why is AVG corrupting the C++ installs? I'm getting really close to demanding a refund. Your anitvirus isn't worth the headache.
Hello there,
I also have the same problem with AVG Zen. The program installs just fine, but when you want to install the Protection thing to become Protected, it fails to install. I am using Windows 10 as well and it is the 0xC0070643 failure to install error.
Please help!
Guys i had this problem for the last 4 months…i thought i was just gonna give up BUT after reading the entire thread there is a solution i found that it worked for me. My system is a Windows 10 x64. I wanted to install the AVG Internet Security but kept getting that stupid error code. I had previous versions with no problems until i installed the 2016 Version. I decided to go back to the old version BUT again that dumb error code would pop up. So this is what i did (Step by Step)
1) Remove AVG thru Windows Settings APP remover (If its not there dont panic…lol)
2) Download the Latest edition of AVG Remover Software
3) Run the AVG Remover Software (This will pop up command promt and run…it will then ask you to restart computer…once u restart the software will finnish running)
4) Remove/Delete the AVG Remover Software.
5) Go Download CCleaner (It's Free, and if u already have it good for you)
6) Run CCleaner with Default checks in place.
7) Now Run the Registry Cleaner on CCleaner (Before you run this you might want to save a log of the entries…it will ask you)
8) RUN REGISTRY CCLEANER AGAIN (this is the key because usually the first time leaves some bits over so you MUST run again 2-3-4 Times etc as long as there is no more registry errors.
9) Re-Start your computer after Registry Cleaning.
10) Install AVG (ANYTHING) and it will run…

Hey!
So I've been running into the same issue as well. Deleted AVG through the AVG removal tool provided in the link, and then try to reinstall AVG Free through the other link provided. Just for your information, been running Windows 10 64 bit and no problems with AVG whatsoever till earlier this month.
Hi there,
I'm having the same issue as well. Just got a brand new laptop for Christmas and I've removed all previous antivirus software it came with, but I'm unfortunately getting this exact error code. Any help would be greatly appreciated. Thanks!
Hello,
Unfortunately I have the same problem as everyone else on this thread. It's my uncle's computer (new Asus laptop with Windows 10). He had a working AVG Free install, but he suddenly (maybe after some other program upgraded) got the error messages about the MS Visual C Redistributable dlls missing and then he tried reinstalling AVG Free to no avail. He brought the computer for me to look at, and I got the dll issue fixed by removing all programs installed by AVG (had to use AVG remover), including the redistributables, and reinstalling. Now, whatever I do, I get the 0xC0070643 exec_finished when trying to install AVG Protection. I have administrator level access to the computer. I tried to look inside the install log cab file, but even though I found the error inside one of the log files, it doesn't help me much. I'm going to send the AVG_SysInfo output to AVG support tonight, unless I figure out some way to fix this problem myself.
Hi Guys,
I was having the same issue and came across this and various other forums. I went to uninstall avg but instead repaired it as other forums had mentioned corrupt instalations.
Once repaired problem solved 
Hope this helps
Hi, I also had the same problem and had follow the previous step u suggest at previous message but still cannot work. I also had try delete the regedit local machine AVG folder then restart and install but still had same issue, pls advice. Thank You.
This is absolutely rediculous.
I have been using AVG for years without any problems until 3AM this morning when Windows 10 did an update. After a restart AVG had a "License Error" and asked me to re-enter my license number…how on earth was I to know my license number for a free version?
At this point i decided to un-install AVG and try to re-install it to resolve the problem.
To my astonishment, I noticed there was an install in my programs and features called "AVG" and "AVG Protection" which was installed today…I did NOT request this software to be installed.
It will NOT allow me to uninstall it, so I have used the AVG Remover tool
Now, It will NOT allow me to install a new version of AVG without it giving me this AVG ZEN software which I do not want…
I really hope this new AVG update is not permanent, as I will simply find an alternative Anti Virus for me personally.
Why should users be sent an Email with further instructions!? Stop wasting our time and put the instructions in plain view of everyone to help them.
This is the second time in a couple of months that I'm unistalling and reinstalling because it is confused about a license key. Each time I run into this same unistall error and use the AVG Remover. Currently I'm uninstalled and running MS Defender - is the offline install fix this problem so it doesn't keep coming back or is it just a way to reinstall?
i am also getting this error - i have submitted an email with the errors
i have a brand new laptop and have removed the mcafee that was installed on start up.
i have been told 'success' and to restart but it has not worked.
before that i recieved the unsuccessful error about 5 times.
please send through an email with instructions on how to solve this.
