I am telling you all of these from my personal research. It isn’t necessary that your error must be due to these issues but some of them might be the cause.
Incorrect command line
We all know that there are different languages like python, c++, java, etc. All these languages are used to develop and run different computer applications. These languages require a specific command line to execute different programs. Similar things happen during the DISM. A user has to input the command line if he or she wants to execute a program properly. Sometimes users put incorrect spaces before the character “/” which is not ok for DISM. As a result, the user face errors like DISM Error 87.

Running Command in command prompt window
The DISM may look like an ordinary command prompt but it is not. If you are trying to run DISM in ordinary command prompt then let me tell you that it will do nothing. You must use DISM in an elevated command prompt window rather than the ordinary command prompt. At least if you don’t want to see any unwanted error messages on your screen.

As I have already said that programming languages work on some rules. If you violate any rule they will never work and the same is the case with DISM. It is a kind of elevated command prompt that uses the specific command line to operate. If you input incorrect command line then you will face an issue like DISM Error 87.
The right command line will have no issues and run properly. Now I am sure you are looking for the right command line but don’t worry I will share the right command lines for both health scan and health restores. You can use these lines and run it on your system.
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
Now you may have noticed that the right command lines have spaces before each “/” character. Yes! sometimes people use the wrong command line and as a result, they face issues. The error they make is that they don’t put the right spaces before the character “/“.

They have also reported that when they switched to the Windows 10 version of DISM with Wofadk.sys filter driver there was no issue at all. Also, check out DISM Supported Platforms for more details.
