Option One: Reinstall Microsoft Visual C++ Redistribution Package MFC Security Update

1) Follow the path: Start button > Control Panel. Choose to View by Category, and then choose Uninstall a program under Programs category. 

2) Check to see what version of Microsoft Visual C++ Redistributable program that you have installed. We are having version 2005 and 2012. Select one from the list and choose Uninstall

3) Then repeat the uninstall process with the other Microsoft Visual C++ Redistributable programs that you are seeing here. 

4) In most case, this problem can be solved by installing Visual C++ redistributable 2015 Redistribution Update 3 downloaded from Microsoft. This is the latest version of the update so far. 

Please make sure that you only download this file from Microsoft and not some random websites. 

5) When the download finishes, double click the installation file to install it on your computer.

6) When the install finishes, reboot your computer for the change to take effect. 

If the problem persists, please follow the next option below.

Option Two: Run SFC Command

1) Press Windows key and X at the same time, then choose Command Prompt (Admin)

When prompted with administrator permission, hit Yes to continue. 

2) In the command prompt window, type in the following command: 

sfc /scannow 

Then hit Enter

It will take some time for the whole process to finish. 

If this process find some flaws with your system files, it will replace them with the new files. 

You need to restart your computer when the scan finishes. 

Option Three: Run a Virus Scan 

There is another possibility why you would run into this problem: virus or malware infection which caused the .dll file unusable. 

To rule out this possibility, please run a full system check with your anti-virus program. Windows Defender alone might not be able to help you with it. You could try other anti-virus programs. 

If the above methods do not help to solve your problem, please:

1) Reinstall the program that shows you this notification. Sometimes, just simply reinstall the program fixes the problem right away. 

2) You can also try to perform a startup repair with your system. 

3) Or if none of the methods work, you might need to consider getting your Windows 10 reinstalled.
