The presence of an on-board computer on the fourteenth VAZ model greatly simplifies the process of diagnosing some faults. Displaying error codes on the BC panel allows you to pinpoint the location of the malfunction. The functions of the built-in device include a self-diagnosis function that allows you to determine the entire list of problems in the machine systems. Often during such diagnostics, error 14 of the VAZ 2114 is displayed. To understand the method for eliminating the problem, it is worth knowing the decoding of the fault number “14”.

Method 1: Troubleshooting Unarc.dll problems
If you carefully read the error message, you will notice that it contains a library named Unarc.dll. Often this is the cause of the failure, so we recommend that you first read the guide to solving problems with this file.

FIX: Origin error code 14-1 & error code 14-7 (5 methods)
Origin is a popular game publishing and distribution platform from EA.
Some users complained that the Origin client for Windows has some recurrent errors that can affect its functionality.
Some of the most frequent issues are Origin error code 14-1 & error code 14-7.
Both of them are installation-related issues and they already have a lot of user complaints on Reddit.
Method 3: Eliminate Cyrillic from the installation path
Error code 14 when unpacking game files may occur due to the presence of Russian letters in the installation path: unfortunately, a considerable part of the software still does not work well with such characters. The solution in this case is simple - install the problematic game in a path that does not contain the Cyrillic alphabet:
- D://Program Files/Games – correct;
- D://Program Files/Games - incorrect.
Sometimes the source of the failure is the username in Russian. Unfortunately, in Windows, renaming an account is not an easy task, so the optimal solution would be to create a new one with the correct name and transfer all the data there.

How to fix the problem
After diagnosis, the problem should be repaired. When reading a signal, it is necessary to check the circuit and devices following it. The most accurate method is to replace the damaged part with a known good one (new). This will eliminate the possibility of incorrect repairs. If the device is in working condition, the lines are checked; usually a primitive test is sufficient. However, if the control unit or relay fails, you will need a special tester and the ability to use it.
Separately, it is necessary to take into account that factory terminals and blocks become loose and oxidize over time. If the contact on the hitch deteriorates, the on-board computer or laptop program will say that the part is damaged, even if it is not.
You can prevent this from happening in the following way.
- Check the condition of the connectors once every 5000 km. The pads should sit in place tightly, without play. If necessary, elements must be replaced with new ones.
- Check plug connectors two to three times a year for oxidation. Oxides reduce the flow of electricity through on-board wiring, which leads to incorrect display of information.
- Experts recommend purchasing and using oil for electrical terminals. The liquid is similar in composition to transformer lubricants. The formula prevents water and oxygen from reaching metals, which prevents them from rusting.
Important!
You can diagnose VAZ 2114 error codes on the instrument panel and ECU yourself, only if you understand the essence of the process. If you don’t have confidence in your own abilities, it is recommended to contact a qualified technician.
Method 6: Checking the status of RAM
The most rare and unpleasant cause of the failure in question is a malfunction in the RAM - it bears the main load during unpacking, and in such a situation all possible malfunctions make themselves felt. Use the instructions below to check the RAM modules and replace them if problems are found.

Connecting to the Origin server if an error occurs
Quite often you can encounter a problem when a particular program cannot interact with the Internet, as well as connect through it to its servers. The same sometimes applies to the Origin client. He, too, can sometimes “delight” the user with a message that he is not able to connect to the server, and therefore is not able to work. This spoils the mood, but you need to not lose heart, but start solving the problem.
How to Fix Origin error code is 14-1 & error code 14-7
Run the Installer as Admin
If you haven't already, try running the Origin installer as Admin.
Depending on your system's configuration, some actions may be reserved for system administrators.
If your system is restricted and you lack admin rights, try asking your sysadmin to install Origin for you.
Disable your VPN & antivirus
Although a VPN is great at keeping your online identity anonymous and secure your connection, it could interfere with Origin.
Not saying that's 100% the case here, but just to make sure, disable your VPN client and check if there's any improvement.
In order to rule off VPNs completely as a cause, you may try closing the VPN client, and even uninstalling it temporarily from your PC.
Make sure to remove any VPN-related components as well, such as additional drivers.
If you are using any antivirus software in your system, try disabling the antivirus temporarily and see if there's any improvement.
