How To Stop The 1921 Error When Installing Microsoft Office 2010
Fortunately, the error you're seeing is actually very easy to fix if you're able to repair the issues that are first causing it to show.
This tutorial is going show you how to resolve the issue you're seeing and prevent it from occurring again.
The error you're seeing is basically caused by the "MDM" (Machine Debug Manager) service.
This is a "Windows Service" which is used by Windows to help control a number of programs and settings on your PC.
Although Services are continually being used by the Windows operating system to help perform a number of coherent tasks, the fact is that they are often causing a large number of problems for your PC as they interfere with the way in which Windows works.
The problem you're seeing is caused by the Windows Installer on your system being unable to run correctly as the Machine Debug Manager will stop it from working.
The way to resolve the 1921 error is to first stop the Machine Debug Manager service from running on your system, and then make sure that your computer is able to run ad smoothly as possible with all the settings it has.
To begin, you should click onto the "Services" applet in the Windows Control Panel and then locate the MDM service.
When you find the service, right-click and select "Stop", which will basically close it and allow your PC to read the installation files it requires.
After you've done that, try installing the program you wanted again and you should find it works.
The next step is to then use a 'registry cleaner' program to fix any of the errors and problems which may have originally caused the error on your PC.
A registry cleaner is a software tool which will scan through your PC and fix the various errors that Windows will have inside, allowing your PC to run much smoother and more effectively.
Although the registry is continually being used to help Windows recall vital settings including the desktop wallpaper and most recent emails of your PC, it's continually being damaged & corrupted - leading to a large number of errors as a result.
To make sure this problem is not a big issue, you should look to use a registry cleaner tool to fix any of the errors your computer may have.
Doing this will not only fix the 1921 error, but also prevent it from returning.
