Tests on the free version showing expired conditions.

[zony]

This time, I downloaded avast_free_antivirus_setup_online.exe, SHA1: 9B980CE0C2354DE2E8F01431FE73DA64318695E2, I believe the file has no errors. Perform a network installation as follows:
1.The program first connects to 23.59.247.249 (USA) and downloads the free_antivirus_setup_online_x64.exe file.
2.free_antivirus_setup_online_x64.exe appears to connect correctly 203.208.43.66 (Beijing Telecom) and connect 23.55.38.41 (USA)  download Program
3.After more than twenty minutes, the program began to connect all over the earth. 5.62.40.221 (Germany) 23.210.203.65 (Tokyo, Japan) 23.2.16.9 (Hong Kong) 117.128.6.11 (Beijing Mobile) 5.62.38.79 (Netherlands) 5.62.53.225 (Czech Republic)。
　　　　If so troublesome, it will be much easier to provide a country option when starting the installation.
４.Ten minutes later, tracert.exe started to connect to 216.58.200.238 (Taiwan), 172.217.160.78 (USA)
５.avastui.exe has connection 203.208.50.62 (Beijing Telecom), which is the correct connection that rarely appears during the entire installation and activation process.
６.After completing the installation, virus database update, and the first scan, the program interface displays "Expired. Please select a protection type."。
７.This time, I tried the four methods provided by this software to activate,even provided 163 email addresses, all failed. a. Click on the left side of the interface to activate, b. Select the protection type button directly in the center, c. Click the new protection type button in the upper right corner notification, and d. Register the program icon.

Get conclusion:
1. The free version shows that the overdue has nothing to do with offline or online installation.
2. The installer cannot accurately determine the user's region. Rarely does the server in the user's area connect properly.
3. The online installer connects to the USA server to download the installer, which causes the installation process to take half an hour.
4. Four activation methods, including the display of the correct activation information "0 days used", but even so, the program interface still shows that the program is out of date, even after restarting windows.
5. The installation and virus database update can be completed online correctly. It is certain that this error belongs to the program itself.

1.Windows10 fresh install offline free version.
2.After installation, the interface shows that it has expired
3.Click Select Protection Type and select the free version.
4.Give back to try premium security for 60 days for free. Choose "no, thank you"
5.The software still shows expired. no change.
View the IP of the software connection during this period:5.45.58.177, 5.62.53.249, 203.208.43.94, 5.45.58.126, 5.45.59.250, 119.81.94.3, 23.59.247.40,
Because it's using China Mobile Broadband.Normal should connect ip 203.208.43.94.
Why can't it finally display protected information like the previous version.

Is there a reason for a second post?

Yes, I haven't seen any response since a similar issue was reported from February 26. I thought it was a network problem. Now test it once more so that people using the free version can see it.

This is the last post, please keep this.

I use the free version on Windows 10 Pro v1909 and don't have your problem.
I never use the online installer. always the off-line.

Since the last update, has your subscription expired and have you performed a clean install?
You'll have to wait for other subscriptions to expire to see if there really isn't a problem.

Just tested it once in windows10 1909 x64 home. After a fresh installation, make sure that the device driver is correct, set the network parameters, connect to the network, and then install the offline installation program of avast. The result still shows that it has expired, and it is exactly the same as before and cannot be resolved. Previously used windows10 1809 x64 home.

Thank you, bob3160 and chris,
I have encountered similar problems before, when my network provider was Great Wall Broadband of China, and now it is China Mobile Broadband. At that time, the problem was solved very well, depending on the information cited. Now, the problem is just repeating itself.
        Now I use the free version of avast19.9.2394, the software interface says "This computer is protected". Occasionally, information about expired messages pops up, but this is acceptable. The latest version shows choosing a protection type, which is weird.
         No subscriptions have been made before.Naturally, there is no subscription expiration.
         The free version has always been very easy to use. After installation, you can use it with peace of mind without any settings.
         

Hi,Jiri Samanek
          Thank you very much for your technical assistance. I have been experiencing this problem for several months.
          I always install a new system, and then install the security software offline, until these are completed, will be networking, it is more secure.
          So, I always install the complete offline installation package.Now that you tell me the latest beta, the full offline installation package does not contain the latest configuration file, so can not connect to the new authorization server. In this regard, I am confused.
          Before, I tested many versions, including: ver 17.7.3660.0，17.8.2318，17.9.2322，18.1.3769，It is now well established that ver 17.7.3660.0, the older version, is doing the best in authorizing administration.It is also because of its good performance, I can be sure, the problem is not in my network service providers and computers.Now ver18.1.3769 also performed better than the previous two versions, which makes me very happy, I believe the next version will be better.
         Believe: Next offline install version, can contain the latest configuration files, including the latest license server address, the perfect solution to the problem of authorization failure encountered offline installation.
         Thank you very much for your security software and your work.

next time you perform a clean install, could you make sure that the "C:\ProgramData\AVAST Software\" folder has been removed and at least that the "license.avastlic" file is no longer in the "C:\ProgramData\AVAST Software\Subscriptions" folder
I performed the procedure (in safe mode of course) last week for a paid product (but it must be the same for avast free because the file "license.avastlic" is also present in the folder) and neither the folder nor the file was deleted, I had to do it by hand before reinstalling avast.
So, in your case, it could be that avast still detects your old license file... outdated .

Each test is a fresh installation of windows, naturally there are no such directories or files.

[chris..]

Ok

1.Windows10 fresh install offline free version.

my brain had read "Avast fresh install offline free version" 

Each test is a fresh installation of windows, naturally there are no such directories or files.

each time you perform a fresh installation of windows?

[zony]

Everyday way:
Download the Windows cumulative patch every month, use dism to integrate into install.wim, install Windows 10 completely, install the driver and make the necessary settings, and use the dism command to back up to a wim file. Format the C drive when needed and use the dism command to restore.
For the 1909 version of the test, decompress the install.wim in the iso directly, use the dism command to decompress it to the c drive, and use the bcdboot command to establish boot and restart into the system.
This saves time for a fresh installation of windows.

[bob3160]

Why bother with an AV if you're doing this monthly?
Sorry but to me this makes no sense.
You must not have very much to do.

[zony]

Yeah, this is all old habits.
Now consider whether to directly use the protection that comes with windows, or other software.
Based on historical experience, such problems cannot be resolved until version 21, and this is the result of some people's insistence on feedback.
This kind of problem occurred in the last 17 editions, and the initial feedback was ignored.

[zony]

It is estimated that avast does not have authorized service sites in China, and there are many foreign sites in the network I use that are unreachable. If so, the reason for this is simple.
