If you are a regular social media user, then you must be familiar with Skype. Skype has been around for about 16 years now and has gained so much popularity over this time.

One common issue that many Skype users report today is getting update errors. Most people don’t know how to fix the ‘Skype update failed to install’ issue in Windows 10, which makes it hard to use the app. All is not lost, though. In this article, we’ll look at this issue in detail to help you understand how to handle it like a pro. Therefore, keep reading to find out.

What is the Skype error code 667?

Most Skype users, especially those running this app on their Windows 10 computers, say that it had been working fine until they tried to install the latest update. Users insist that every time they try to install the update, they get the error 666/667 response.

You are most likely to experience this response if there’s any kind of file corruption on your machine. So, you can get the Skype error code 667 if your computer shuts down abruptly when you’re installing the latest update. Also, this error might occur if an AV scan quarantines crucial files related to Windows Update.

Skype errors such as 666 and 667 are very common nowadays, and you’re not the only one facing them. You can solve these errors by conducting DISM and SFC scans to resolve any file corruption that might have occurred.

Conducting these scans is not always easy, which is why we’ll discuss them in more detail. Below are some of the best ways you can fix the errors:

1. Run DISM and SFC Scans

One of the best ways that you can fix these errors is by conducting DISM and SFC scans. The great news is that Windows has built-in features that allow you to do these scans, thereby enabling you to get rid of any corruption that might be causing the 666 and 667 Skype errors.

System File Checker (SFC) is a utility in your computer’s operating system for detecting file corruption. Therefore, running it allows you to check the integrity of every system file on your computer. That way, SFC can identify damaged, changed, or corrupted system files and replace them with correct and safe ones where possible. When SFC can’t help to fix the corruption, that is where DISM comes in.

Deployment Image Servicing and Management (DISM) refers to a more advanced Windows utility that performs several functions. DISM can solve more complicated issues, which is what makes it vital to perform both DISM and SFC scans. Remember that it is crucial to back up your data before doing any of them.

How to Do a DISM Scan

To run a DISM scan:

1. Click on the Windows key to access the Start menu.
2. On the search bar, type “cmd.exe” and wait for a moment.
3. Right-click on the cmd.exe result, then choose the Run as administrator option. Doing this will help you run the scan effectively since you have more privileges.

You can even run DISM in dry mode to see the existing corruption on your computer without fixing the issues first. Doing this is hugely advisable since it shows you what you are dealing with, thus enabling you to come up with the best solution.

There are several DISM checks that you can perform. Here are the most important ones that you should consider:

1. a) DISM /Online /Cleanup-Image /CheckHealth

This scan checks the corruption flag in a certain image and then returns the results to you before doing any repairs. This scan mostly takes less than 2 seconds.

1. b) DISM /Online /Cleanup-Image /ScanHealth

Typing this command in CMD will show you if there’s some component store corruption. Doing this scan might take longer compared to the DISM /Online /Cleanup-Image /CheckHealth scan. It brings the results to the CMD window. Also, this scan does not correct any issues it finds.

1. c) DISM /Online /Cleanup-Image /RestoreHealth

This scan is the most vital one as it checks for corrupted files and tries to repair some issues automatically. This scan might take longer than others, especially if it finds lots of corruption on your computer.

When doing this scan, it’s crucial to note that it can sometimes appear stuck. Therefore, if you notice such behavior, be patient as it will continue running automatically after a moment.

The best part about using DISM is that it attempts to correct Windows Update issues, which is where your Skype will benefit from.

How to Do a System File Checker Scan

To conduct an SFC scan, do the following:

• Type CMD on your search bar.
• Run CMD as an administrator.
• If you want to check and repair the entire OS, then type “sfc /scannow” (note that there is a blank space between sfc and the slash symbol).
• Type sfc / verifyonly if you just want to verify the OS.

You might have to run an SFC scan several times to fix more problems. After completing the scan, you’ll see one of the following responses:

1. Windows Resource didn’t find any integrity violations. This result means your computer doesn’t have corrupted or missing files.
2. Windows couldn’t perform the operation. To help solve this, do an SFC scan in safe mode, making sure the PendingRenames and PendingDeletes folders are under %WinDir%\WinSxS\Temp.
3. Windows found some issues and repaired them successfully. This response is usually great news since the Skype issue has most likely been solved.
4. Windows Resource found issues but couldn’t fix all of them. You can find the details of this scan in CBS.Log %WinDir%\Logs\CBS\CBS.log.

Doing SFC and DISM scans is vital as it allows you to check for any corrupt areas that might be causing the errors. That way, you can easily determine if it’s the computer that has an issue or whether you need to install a new app. You must restart your PC after conducting SFC and DISM checks. Then see if you can now install the updates. You may also need to make Skype and the entire computer faster.

2. Install the Latest Skype App Manually

Microsoft always ensures there’s an updated version of Skype on its official website. So, you can uninstall the old version on your computer and install the latest one. Doing this helps to avoid dealing with the updates that are tricky to install.

By now, you should know how to fix the Skype error code 666. In this article, you can find the major ways to fix the 666 and 667 Skype errors. Conducting DISM and SFC scans is usually the most effective option, but it can seem tricky to some. Therefore, you can also consider uninstalling your app and then reinstalling it to see if that solves the problem.

You should also conduct thorough research to see how to get rid of the ‘Skype update failed to install’ error more effectively and easily. You should choose one method and research it to increase the chances of fixing the issue successfully without causing more problems.
