How to Fix Msteams.exe Bad Image Error?

Windows 11 has a built-in Chat app powered by Microsoft Teams. It lets you text and call your friends, relatives, or colleagues using a shortcut on the taskbar. Microsoft Teams and its Chat app launch by default in the background every time you turn on your computer. Therefore, you might encounter a weird msteams.exe Bad Image error. It could also appear when you launch Microsoft Teams using its shortcut or the All Apps list.

The msteams.exe Bad Image error contains the following text:

“C:\Program Files\WindowsApps\MicrosoftTeams_21224.700.938.1333_x64__8wekyb3d8bbwe\zlib1.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. Error status 0xc00000020.”

Besides zlib1.dll, the error sometimes refers to other files, such as VCRUNTIME140_1.dll, WebView2Loader.dll, and VCRUNTIME140.dll.

We should point out that the msteams.exe Bad Image error is often a result of messing around with WindowsApps’ security permissions. That is the folder where Windows 11 stores apps downloaded from the Microsoft Store. Users sometimes want to dig into it to mod apps and games, pirate them, or perform other types of tinkering. We do not recommend changing the ownership and security settings of the WindowsApps folders. Experimenting with that area often results in apps crashing and showing various errors, including msteams.exe Bad Image.

If you have already changed security settings and do not know how to get everything back to its original state, the only way to fix the problem is to use a system restore point or reinstall Windows.
