We had a look into the issue and discovered that it is typically caused by the following factors:

Generic glitch – In cases where the problem is caused by an already documented genetic glitch by Microsoft, you should be able to resolve it automatically by running the troubleshooter and applying the recommended fixes.Corrupt Windows Update components – Your operating system relies on Windows Update components to install the recent updates. If any one of the components becomes corrupt, you are likely to face issues like the one at hand.Glitched Windows Store installation – Additionally, it’s possible to encounter this issue as a result of an issue that impacts UWP applications as a whole. Users who found themselves in a similar scenario have reported that by running a Powershell command that reregisters the application, the error code 0x8700017 was permanently resolved.Networking error – You might also be facing the issue if a corruption error or bug is affecting your network settings. This issue can be resolved by restarting the router or running the built-in network troubleshooter.

Now that we know about the potential causes, let’s have a look at some effective troubleshooting methods to fix the issue at hand.

Reboot Your Router

The first thing you should try if you are having trouble installing updates is to reboot your router since errors like the one at hand are commonly caused by temporary software/communication glitches.  Such glitches can be easily resolved by restarting your router. If doing so does not do the trick for you, then proceed with the next troubleshooting method below. 

Run the Internet Connection Troubleshooter

Microsoft Windows 10 also includes a troubleshooter tool that is useful for diagnosing and fixing common network problems. Typically, the troubleshooter can fix the issue within a short amount of time if it is caused by a connection bug in your system.

Reset the Network Settings

You can also try resetting the network settings to fix internet and connectivity problems and error code 0x8700017. Performing a network reset or resetting network settings restores all network-related functions and settings to their original value; just like a factory reset.  Resetting your network settings will delete your Wi-Fi name and password, Bluetooth device connections, VPN settings, and cellular network preferences like data management.

Reset the Windows Update Components

You also might not be able to install the app and face the error code 0x8700017 if the Windows Update components on your Windows are corrupt. The solution is simple to this problem; all you have to do is reset the components to get them up and running again.

Reinstall the Microsoft Store 

There is also a chance that your Microsoft Store installation is corrupt, due to which you are unable to install updates like the one under consideration. In this case, reinstalling the Microsoft Store might be able to help you download the app update without the error code 0x8700017. It is important to note that there is no option to reinstall an application within the Microsoft Store. The only way to do this is to use PowerShell as an administrator. 

Change the DNS Settings

A domain name system is vital to all internet activities. When your DNS server is slow, or not configured properly for caching, it can slow your connection, leading to errors such as the one at hand. Fortunately, it is possible to improve your browsing speed by modifying the DNS settings or changing to a DNS server that is optimized for efficiency. In this method, we will modify the DNS settings in Windows to resolve the error code 0x8700017.

Perform a Repair Upgrade

If you have come this far without a solution, then this implies that the error code 0x8700017 cannot be solved using conventional troubleshooting methods.  If this scenario is applicable, then pretty much the only thing you can do is perform a repair upgrade. During a repair upgrade, the system files are repaired, and the latest windows updates are installed. Hopefully, this will fix the issue once and for all.
