Running Windows 10 AVG Free edition
Update does not complete and gives a message "Update has detected running installation.  Complete that installation before starting update"
I cant find any other installation running
I cant uninstall because it comes up with the same error message.
Any suggestions please?

Had same problem.  Followed advise on another chat to stop "Windows Installer" in Task Manager and then run the AVG update.  Worked fine.  Seems to be a bug in Windows 10.
"Error loading type library/DLL (0xC007001D)"

Dear Avinash ~ I am afraid to say that the two applicable download installation files AVG_Antivirus_Free_692.exe and AVG_Antivirus_Free_x86_694.exe (32 bit) on the above link: 
http://www.avg.com/us-en/download.prd-afh-free produce the same error message as posted at the very top of this thread.
However,  SUCCESS! SUCCESS!  using:
http://files-download.avg.com/inst/av/avg_free_x86_all_2015_ltst_222.exe, kindly offered by Norton Fern above and obtained from:  https://www.techmesto.com/avg-2015-offline-installer-standalone/

The installation file worked perfectly and I am now running AVG Antivirus Free 2015 (Build 6140).

Somehow, AVG, it would seem a critical "difference" has crept into some of your installation files.

Same here. Temporarily disabling AVG kind of does the trick, it load the mails, but all attached files downloads show as failed, and won't go through. I did upgrade to 2015 just in case, to no avail.
We can't "just" disable temporarily several times a day, we're going to need a proper fix guys. As in, an update. Thanks in advance. :)

Thanks Diego. for Error:0xC0070643, you can try running AVG Remover from http://www.avg.com/ww-en/redir?url=http%3A%2F%2Fdownload.avg.com%2Ffiledir%2Futil%2FAVG_Remover.exe&urlSec=UhT%2BBzZUdTGTfMN%2BMUDefLYjJIc5sr9PT4gwqqdOZLdqTfL1KgHh6k4Nsq3ZpPAN%2FWp9nmon7o%2BnrfxaAPzsIh9Vwf6qvehmwRbhQo2mKZ8jYhWRDvz2QC4zWJ3vHjKQ (http://www.avg.com/ww-en/redir?url=http%3A%2F%2Fdownload.avg.com%2Ffiledir%2Futil%2FAVG_Remover.exe&urlSec=UhT%2BBzZUdTGTfMN%2BMUDefLYjJIc5sr9PT4gwqqdOZLdqTfL1KgHh6k4Nsq3ZpPAN%2FWp9nmon7o%2BnrfxaAPzsIh9Vwf6qvehmwRbhQo2mKZ8jYhWRDvz2QC4zWJ3vHjKQ)    ---- you need to run it twice. (NOTE: after it removes the AVG prog, it will ask you to restart it, DO NOT restart the computer yet and just leave that window open and you need to run it again) Then go to programs and features, after you have run the avg remover,  arranged the programs listed by "publisher" , you will have 1or2 programs that will be left behind under AVG as the publisher, you need to uninstall this as well, once you've uninstalled it, restart your computer. After it restarts, reinstall the AVG again.

Please let us know if it will give you same error. Thanks

We are a managed service provider who inherited a mess from a previous company. They were using AVG free on about 100 computers in the corporate environment. And maybe another 50ish computers with old outdated AVG versions.

We need to mass uninstall AVG. I downloaded the AVG removal tool, but there does not seem to be any switches I can use with it.

I have tried
removeavg.exe /norestart /skipask /silent /
But the normal prompt still pops up

I am not going to walk around to 100+ computers and manualy uninstall AVG. How can I get the removal tool to work on a domain wide basis on all the machines at once, silently without interupting the users?

Alan, we didn't install AVG free in teh corporate environment, the previous IT guy did, we are trying to clean up his mess. And AVG support is less than helpfull with it.

FYI solved the issue myself. Posting it here for the next person, so they don't have to ask/ deal with AVG support for a simple answer

"C:\Program Files (x86)\AVG\AVG2012\avgmfapx.exe" /Appmode=Setup /uninstall /uilevel=Silent /dontrestart

Any ideas?

Any pointers would be appreciated!

During my first two years of subscription AVG would defragment and remove clutter.  Now Fix Performance hangs at 23% and will not move past that on Windows 10.  Do I have to pay extra or is Fix Performance part of AVG Pro?

Hello guys!

I have two problems with AVG ZEN and AVG Protection:

1- I install AVG Zen (no problem)
2- Then I install AVG Free (no problem)
3- Then, everytime I log this device with AVG Free to my AVG Zen network as Admin. As soon as I do it, it starts to update and when it finishes it changes from AVG Free to AVG Internet Security without asking if I want. Also, it seems that the internet security is just the layout, as the features of it remains the same that are availabe on the free version. However it says on AVG ZEN that is will expires in 30 days.

Other problem is AVG ZEN with Avg WebTune Up:

1- I instal AVG WebTune Up.
2- If Chrome is default browser, I follow the install procedure and no problem happens.
3- If Firefox is default, I click on the restart browser button on AVG ZEN, it opens the firefox browser, installs the plugin successfully, but the restart browser alert in AVG ZEN keeps showing as a Yellow Circle. Even if it is installed successfuly. Only if I change the default browser to Chrome it becomes green.

How to solve this probem too?

Thanks for your time!

How could I solve this?

Hello Bruno,
Thank you so much for elaborating the issue. We apologize for the inconvenience caused. I would like to keep you informed that AVG ZEN is the interface to install certain AVG programs. Please note that 'trial' version of AVG programs have limited validity. Once the 'trial' period is over, the program will automatically be changed to AVG Free. Regarding the issue related to AVG Web Tune Up, I would like to keep you informed that AVG Web Tune up is currently supported only for 'Chrome' browser and does not support for other web browsers. This is a known bug that is being solved by our developers. It has P1 (high) priority so it should be fixed soon. Please note that your device is FULLY protected even without Web Tune up component. Please feel free to contact us for any further assistance. Thank you.
