There are two ways that we can remove MSE. The first was alluded to before in one of the threads and the other one is running a cleanup tool and they vary in difficulty.

First:
1. Download the *OneCare cleanup tool: http://go.microsoft.com/fwlink/?linkid=81699
2. After the tool runs if it prompts for a reboot please do so.
3. Reinstall MSE.

Second:
1. Download MSE from the website and save the file on the Desktop.
2. Open Command Prompt through RUN or Start Search by typing CMD hit enter. If you are using Vista right click on CMD and select "Run as Administrator".
3. In the Command Prompt console type: CD %USERPROFILE%\Desktop <- Hit ENTER
4. Type: msse <- then hit the TAB button.
5. Depending on your Operating System, after hitting tab it should either appear as any of the three below:
        mssefullinstall-x86fre-en-us-xp.exe
          mssefullinstall-x86fre-en-us-vista-win7
          mssefullinstall-amd64fre-en-us-vista-win7.exe
6. Now put a space in between the whole line and put /U as seen below:
        mssefullinstall-x86fre-en-us-xp.exe /U
          mssefullinstall-x86fre-en-us-vista-win7 /U
          mssefullinstall-amd64fre-en-us-vista-win7.exe /U
7. Hit ENTER and this should uninstall Microsoft Security Essentials.
8. After the uninstall you can now attempt installation. It would be best that you restart your system first after the uninstall.

*this tool is for OneCare but works also in removing other MSE components and entries which will enable re-installation of MSE.

Its a command-line switch CD is for "change directory" alternatively is CHDIR. The %USERPROFILE% is an environment variable to switch the path of the current prompt to the current user profile. This should be true in XP, Vista and Windows 7. Its universal.

For your reference:
FOR XP - http://vlaurie.com/computers2/Articles/environment.htm
For Vista and W7 - http://vistaonwindows.com/environment_variables.html

The reason we will need the command-line switches is to prompt the MSE installer to uninstall, thus the /U switch after.
Also, one reason why I suggested to SAVE the file into the DESKTOP. Notice the whole command line:
CD %USERPROFILE%\Desktop
Do not forget the spaces in between CD and the %.

I am having the same errors 0x800070715 and 0x8004ff0B. I did clear my computer of any other antispyware. MSE did download ok. Now, I am dead in the waters.

I have tried the window onecare cleanup tool twice. No luck. And I have tried the CD %userprofile%desktop<-. The results is the file can not be found. I have also tried the window install cleanup. No luck.

Is there another way to uninstall MSE?

Thanks

The correct syntax should be: CD %USERPROFILE%\DESKTOP

Do not forget the space between the CD and the % sign. There is also a \ after the Desktop.

The file for the MSE Setup or installer should be saved on the Desktop.
If you saved the MSE setup in another location, the syntax for the command will definitely not work.
Kindly move, copy or save the MSE Setup/Installer file to the Desktop first.

Error message numbers? Exact wording?
Are you trying to remove MSE? Or install it?
Any other security software installed?
