**Summary**  
If you have installed the Mattermost Desktop client at the same time as 7-Zip on a Windows 10 computer, you can no longer extract archives with 7-Zip using the Windows Explorer context menu.

**Steps to reproduce**

- Install 7-Zip (version 19.00) (at our company: via SCCM)
- Install Mattermost desktop client (version 4.6.1) (at our company: via SCCM)
- Open windows explorer and right-click on a .zip/.7z/.tar file =\> 7-Zip =\> Extract files…
- an error message will pop-up (see “Observed behavior”)

**Expected behavior**

- While clicking on “Extract files…” a 7-zip dialog should appear

**Observed behavior**  
Error message: “Das System kann die angegebene Datei nicht finden. C:\Program Files\Mattermost-desktop\resources\app.asar.unpacked\node\_modules\7zip\7zip-lite\7zG.exe”  
(“The system cannot find the specified file”)
