Many netizens will pop up a prompt box "Unable to locate the program input point on the dynamic link library" when opening the program on the computer when using the computer, which makes the netizens very annoyed. After analysis, we summed up the following solutions, which can completely solve the problem of "unable to locate the program input point on the dynamic link library".
What happens when the dynamic link library cannot be located?
Phenomenon 1: When the computer is turned on, the prompt box "Cannot locate the dynamic link library" will pop up.
Phenomenon 2: When running online games or stand-alone games, the prompt box "Unable to locate the program input point on the dynamic link library" will pop up.
Phenomenon 3: When running a certain software, it shows that the program input point cannot be located.
What is a dynamic link library?
Dynamic link library is abbreviated as DLL in English. It is not an executable file. It is an encapsulated library that can provide common code functions and data to multiple programs. Some functions and data needed by programs are encapsulated in DLL files in advance, and these DLL dynamic link libraries can be called by the main program when the program is running.
So what causes the failure to locate the program input point on the dynamic link library?
A, computer infection caused by Trojan virus.
Nowadays, many Trojan viruses will replace system files and rename real system files, such as WININET.dll, Msvcrt.dll, usp10.dll, midimap.dll and lpk.dll. Many anti-virus software did not change the modified system file name after removing the Trojan horse, so when opening the program to call the system file, a prompt box "Unable to locate the program input point on the dynamic link library" will appear.
The typical virus is the kidnapping Trojan, which is a new type of extremely destructive Trojan. Different from the traditional virus, it is booted by kidnapping the system file dll.
The Trojan virus mainly shows:
The computer runs very slowly.
It takes a long time to get into the desktop.
The program runs very slowly.
Mainstream antivirus software can’t be opened normally, and reinstalling the system can’t solve the problem.
Although the vast majority of anti-virus software has become humanized, once some Trojan viruses are found to be bound to system programs, many anti-virus software directly delete these maliciously kidnapped system programs (which may include DLL files), resulting in the lack of necessary DLL dynamic link libraries for systems or applications, resulting in the problem of "unable to locate the program input point on the DLL".
Solution (repair method)
(a), software repair method:
1. Jinshan Guardian
Enter the main interface of Kingsguard, select "Kill Trojan Horse", and then click "Quick Scan". Through Kingsoft Guard’s killing of Trojan virus, it can also repair related dll components.
2, giant shield Trojan killing tools
These problems can be solved by using the memory scanning of giant shield. Giant shield memory scanning will not only remove Trojan files, but also restore the system files modified by Trojans, so that when you open the program, there will be no problem that you can’t locate the program input point on the dynamic link library.
3. Download and install mainstream anti-virus software (NOD32, Kaspersky, antivir, Avast, McAfee, Norton, Rising, Kingsoft Internet Security, 360 Security Guard, etc.), and completely kill the virus after updating the virus database.
(2), manual repair method:
Remember the dll file mentioned in the pop-up prompt box "Unable to locate the program input point on the dynamic link library", and record the missing *.dll prompted by the system. Focus on checking whether the file is abnormal, and copying a copy of the dll file to the corresponding directory (folder) can basically solve the problem.
1. Download the required dll file.
Search for the required dll file through Baidu, enter the required *.dll (with dll suffix, such as WININET.dll) into the search box, click the "Baidu Click" button, select the website where you want to download DLL from the listed pages, and enter and download the required *.dll file.
Note: When searching, you must install anti-virus software and open the firewall, so as to avoid computer poisoning caused by the problem that you can’t locate the input point of the program.
2. Restart the computer and press F8 to enter the safe mode.
3. Copy the downloaded *.dll file to the C:windowssystem32 folder (directory).
4. Restart the computer to solve this problem.
Note: If the game program lacks a DLL, you need to copy the DLL to the specified location in the game directory after downloading (because there are many games, the required DLL and location are different, which requires you to explore in practice).
Two, update the program, upgrade a software (or game).
When the software or game is updated online, the DLL files that should be written or overwritten normally are not downloaded and updated successfully due to unexpected power failure, restart, writing errors and other reasons, resulting in the lack of necessary DLL files in the running process of the software or game and reporting errors.
Solution (repair method): Generally speaking, cover the installation can solve the problem.
Third, deleting system files at will is caused by the user’s own operational mistakes.
The user accidentally deleted the DLL file in the program installation directory by mistake, which led to the failure to find the corresponding file when the program started and reported an error.
Solution (repair method): In this case, we need to carefully recall what we did before the problem occurred, and download the software cover the installation again or copy a system file with the same name on another computer. These treatments can also solve the problem.
If the above method cannot solve the problem of "unable to locate the program input point on the dynamic link library", please reinstall the system, software or game.
