Hello, everyone. Since the website was created, it has been affirmed by many people. Thank you for your trust and support for pconlife.com. For a long time, the webmaster has also helped many people successfully solve various problems.Many people often write to ask me, why after downloading and overwriting the file, the error still exists ? I want to say, you have to understand one thing, that is, if your system is normal, the hard disk is not damaged, the file will not miss for no reason.

Many computer users sent us feedbacks that they encountered some weird problems. For example:
1. The system shows up "the file is running, it can not be overwriten..."
2. The overwriten file could be edited or destroyed after a while or restarting OS.
3. What's more, even though the file was overwriten, the problem was still there. These were weird.

Generally speaking, under the premise that the operating system is normal, you only need to download the corresponding file to replace it, and the software can run normally. However, sometimes after download the corresponding files, the software still cannot be used normally, and it is nothing more than the following reasons:

Files are often damaged or lost. It is because the hard disk is used for too long, which will produce some bad sectors. This is inevitable. The files stored on these bad sectors will naturally be damaged or lost. First try to use this Disk Data Recovery Tool to restore the data, and check whether the hard disk has bad sectors, shield these bad sectors.

Some software or drivers fail to start, even if the software or drivers are uninstalled and then reinstalled, they cannot run normally. A large part of the reason is that the uninstallation is incomplete, and there are some old data remaining in the system registry. It is recommended that you use the professional Uninstall Tool to uninstall all the old data in the registry, and then reinstall the program.

The system has always been running normally, but one day, some software or drivers suddenly become unavailable, or the system is unstable, and some error prompts often pop up. It may be that the system is infected with a certain virus, and this type of virus does not aim to destroy the system, but to steal personal information, so the system can still operate. However, the virus needs to start with the system, so the virus will inject itself into the core process of the system, which will lead to the instability of the system, causing some inexplicable problems. You can upgrade the virus database of your anti-virus software to the latest and check the system. If you really can't find out anything, you can try to use this Anti-virus Software , which is currently the anti-virus software with relatively strong anti-virus capabilities, it has a good ability to block the current popular ransomware.

In addition, there are some more practical tools:

The operating system generates some temporary files every day. After using for a long time, many junk files will be generated. These files will take up a lot of disk space and make the system run slowly. You can use Remove Junk File Tool. This tool is very practical and is often used.

In the face of increasingly rampant ransomware and information theft viruses, if you are worried about losing (or forgetting) some important account information and passwords, or being stolen by hackers, you can use password protection to save these data. It can protect your important information very well.

The above software is recognized after the webmaster's long-term work through practice and comparison. we hope you can protect your operating system well and keep your important information safe at the same time.

1 Considering the safety, lots of browsers stop downloading the EXE and executable file DLL. Meanwhile, some executable file is so big. And it will take you lots of internet resources as you are downloading the file. So, to fix the problem, we supply the files download with ZIP form in our site.

In this case, it is obiviously shown that your system is infected by virus or is controlled by malware software. Thus, at the beginning, you need to delete the virus or malware software completely. And then, you could overwrite the target file with original system file. If you have not installed antivirus yet, you could select one of the famous antivirus programs.

Please restart your system, and go into the Safe Mode of Windows. And try to overwrite it again. And the job can be easily done.
