Windows Errors

Troubleshooting tutorials on various types of system errors, application errors, caused by virus infection, registry corruption or any other type of malfunction in Windows operating systems.

How to fix RunDLL error in Windows 10

On the initial basis, RunDLL (also RunDLL32.exe) is an integral file of Dynamic Link Library modules that function in correlation with the Windows Registry. The proper operation of all DLL files is meant to ensure faster response speed and memory management while using various apps and Windows processes. If one of such files has been deleted, is missing, or Windows is simply unable to verify its location, the system will prompt a box alert with a relevant message about the error that happened. DLL files stated in error messages can vary vastly, depending on which one of them failed to undergo successful verification by Windows. We have already had multiple guides dedicated to some popular RunDLL errors with files like MSVCP110.dll, D3D12.dll, VCRUNTIME140.dll, CONCRT140.dll, MSVCR110.dll, and API-MS-WIN-CRT-RUNTIME-l1-1-0.dll as well. As a rule, users who receive RunDLL errors can encounter messages with slightly different content and also a specified directory where the file could not be found.

How to fix ERR_CONNECTION_CLOSED error in Google Chrome

ERR_CONNECTION_CLOSED is a frequently-encountered error when trying to open some page in the Google Chrome browser. It happens when Chrome fails to establish connection with a page being loaded - and that is quite obvious. The reason for that, though, could be one out of many. For instance, it could be your third-party antivirus intentionally preventing connection with its firewall setup; a conflict caused by installed browser extensions; misconfigured Internet settings; and other issues as well. Luckily, our solutions below should be enough to forget about the problem and start using the necessary page or pages again. Follow along and try each of them until one finally does it.

How to fix Mail App error code 0x8000000b

0x8000000b is a widespread error that some users may face while trying to add a new third-party account (Gmail, Outlook, Yahoo, etc.) to the native Mail app on Windows. This application is built-in and can be extremely useful for managing emails in different accounts without leaving the desktop. The reason why such an error occurs is problems with syncing - that the Mail app is unable to establish a connection with an external e-mail server. This can happen due to some third-party or even native firewall blocking connection requests, disabled POP and (IMAP) settings, or even a bug in the Mail app itself. As a result, a message saying "Something went wrong. We're sorry, but we weren't able to do that." stretches over the screen and stops users from adding the account. In rarer cases, the same error may also take place when trying to send an e-mail message from one of the already-added accounts. Whatever it is, we have a list of solutions that might be able to help. Follow our guide below to try each one of them and deal with the problem eventually!

How to fix ERR_HTTP2_PROTOCOL_ERROR in Google Chrome

ERR_HTTP2_PROTOCOL_ERROR is quite a popular error that may occur in any browser including Chrome, Edge, Opera, Firefox, and so forth - mostly on Windows 10/11 systems. HTTP2 is a new protocol that replaced its HTTP precursor with a faster time response by consolidating files into one packet and transmitting them to the server. One of the reasons why ERR_HTTP2_PROTOCOL_ERROR occurs is because the website you are trying to visit does not support the HTTP/2 protocol - often due to cheap hosting or that the administrator of the website has not enabled this protocol on the server. This reason would be relevant if you are unable to visit one specific webpage. Otherwise, if that is the entire browsing you are facing problems with, then it could be related to more general causes like outdated browser versions, incorrect date & time settings, conflicting browser add-ons, overstuffed cache, or even experimental features leading to connection conflicts. Below, we have compiled a guide with solutions that will potentially resolve the problem and get your browser back to working again. Note that the instructions below are mainly focused on resolving the problem in Google Chrome, however, you can also use them for performing similar actions in other browsers too.

How to fix Windows Update error 0x800f0831 on Windows 11

0x800f0831 is a Windows 11 error that can be encountered while trying to download-install a new cumulative update onto the system. In the majority of cases, users reported this problem to occur when dealing with KB5008212, KB5005033, or KB5005190 updates. Although the reason for this specific issue is indefinite, the information collected indicates it can be related to corrupted/missing system elements, internal bugs, or conflict caused by third-party software. Whatever it is, you should try each solution we attached below ranging from easier to more complex ones. At some point, one of them should sort out the problem eventually.

How to fix missing api-ms-win-crt-runtime-l1-1-0.dll file error on Windows 10

These are the kind of messages one will receive if the api-ms-win-crt-runtime-l1-1-0.dll file is missing or cannot be located: "The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer", "There was a problem starting api-ms-win-crt-runtime-l1-1-0.dll. The specified module could not be found.", "Error loading api-ms-win-crt-runtime-l1-1-0.dll. The specified module could not be found.", "The code execution cannot proceed because api-ms-win-crt-runtime-l1-1-0.dll was not found. Reinstalling the program may fix this problem.", "api-ms-win-crt-runtime-l1-1-0.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.". The most common reason why such errors occur is a lack of Visual C++ Redistributable elements, file corruption, or faulty software that you are attempting to run. Due to one of these causes, users are unable to run specific applications that require the file. It is possible to face the same or similar error like MSVCR110.dll, CONCRT140.dll, msvcp110.dll, VCRUNTIME140.dll, and so forth in any Windows OS. In essence, this error should not be a big challenge to solve on whatever Windows version you use (be it 7, 10, or 11). We have delivered a complete tutorial with solutions that might potentially work down below.
