From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 2 – Put your PC in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.

When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application. This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

Option 1 – Run System File Checker scan

The first thing you can do to fix the error is to try running the System File Checker or SFC scan. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.

3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 2 – Troubleshoot the missing Msvcr120.dll_clr0400.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the application again.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
