If you have encountered the DISM Error 87 on your Windows computer, don't worry! This error message typically appears when you are trying to use the Deployment Image Servicing and Management (DISM) tool to repair or modify your system image, but it can be easily fixed. In this article, we will guide you through the steps to resolve the DISM Error 87 and get your computer back on track.
What is DISM Error 87?
DISM Error 87 is an error code that indicates the destination folder or file you specified for the DISM tool does not exist. This error can occur due to various reasons, such as incorrect command syntax, missing files, or corrupted system files. When you encounter this error, you may see a message like "The source files could not be found" or "The parameter is incorrect."
How to Fix DISM Error 87
Method 1: Run DISM with Correct Syntax
The most common cause of DISM Error 87 is incorrect command syntax. To fix this error, you need to ensure that you are using the correct syntax when running the DISM tool. Follow these steps:
- Open Command Prompt as an administrator. To do this, right-click on the Start button and select "Command Prompt (Admin)."
- Type the following command and press Enter:
Dism /Online /Cleanup-Image /RestoreHealth - Wait for the process to complete. This may take some time, so be patient.
- Once the process is finished, restart your computer and check if the DISM Error 87 is resolved.
Method 2: Check and Repair System Files
Another possible reason for DISM Error 87 is corrupted system files. You can use the System File Checker (SFC) tool to scan and repair any corrupted files on your computer. Here's how:
- Open Command Prompt as an administrator.
- Type the following command and press Enter:
sfc /scannow - Wait for the scan to complete. The SFC tool will automatically repair any corrupted files it finds.
- Once the process is finished, restart your computer and check if the DISM Error 87 is resolved.
Method 3: Check File and Folder Permissions
Sometimes, DISM Error 87 can occur if you don't have the necessary permissions to access the destination folder or file. To fix this, you can check and adjust the file and folder permissions. Follow these steps:
- Right-click on the destination folder or file that is causing the error and select "Properties."
- In the Properties window, go to the "Security" tab.
- Click on the "Edit" button and select your user account from the list.
- Make sure the "Full Control" option is checked for your user account.
- Click "Apply" and then "OK" to save the changes.
- Try running the DISM tool again and check if the error is resolved.
Method 4: Use a System Restore Point
If none of the above methods work, you can try using a system restore point to revert your computer back to a previous state when it was working fine. Here's how:
- Open the Start menu and search for "System Restore."
- Click on "Create a restore point" from the search results.
- In the System Properties window, click on the "System Restore" button.
- Follow the on-screen instructions to select a restore point and restore your computer.
- After the restore process is complete, check if the DISM Error 87 is resolved.
By following these methods, you should be able to fix the DISM Error 87 on your Windows computer. If the error persists or you encounter any other issues, it is recommended to seek further assistance from a professional or visit the official Microsoft support website.
