4 Guidelines in Fixing DISM Error-50 on Windows: Reasons and Solutions

Are you curious why the error message Error: 50 - DISM appeared on your screen? This post will explain why you should run DISM in the Windows 10 recovery console and how to do it without getting this issue. This error message appears because you attempted to execute DISM from the Windows 10 recovery console with the /Online option selected. Only Windows operating systems that are currently running can be used to execute the DISM command with the Online parameter.

As a result, the command fails when executed from Windows 10 or any other Windows recovery console because the OS is not active there. This article will demonstrate two fixes for this problem message and how to run DISM correctly. The first approach demonstrates how to resolve this problem message without a Windows 10 installation disc.

DSIM Error-50

Part 1. What and Why Dism Error-50

Deployment Image Servicing and Management, also known as DISM, is a command-line utility. It can prepare, alter, and repair Windows installation images, including the images for Windows Setup, Windows PE, Windows Preinstallation Environment, and Windows RE or Windows Recovery Environment. System crashes and other issues are frequently fixed using DISM. However, upon executing any of the DISM commands listed below, some users saw an error 50 DISM does not support servicing Windows PE with the /Online option message:

  • 1. Cleanup-Image Dism / Online / CheckHealth
  • 2. Clean-Up-Image / ScanHealth / Dism / Online
  • 3. Clean-Up-Image / RestoreHealth / Dism

Why does this mistake occur? The DISM utility mistakenly believes you are running the commands under Windows while using the program on a live operating system. A registry key that was misplaced is to blame for this. Furthermore, when customers attempt to run specific commands using this tool included with Windows 10, they receive the DISM 50 error. The operating system assumes that the location from which the command is executed is inside WinPE, which is the primary source of this issue or Windows environment pre-installation. A misplaced registry key is actually to blame for this Windows assumption.

You are all aware that DISM is typically used to prepare and refresh a Windows image, but it also aids in file repair when a system inspector identifies corrupted files based on the scan results. However, DISM error 50 hasn't been the subject of many recent user complaints. They have been running the DISM command on their machines, but they keep getting the same error message.
