Sometimes a computer does not boot properly due to some specific software installed on the computer. You can boot into Windows Safe Mode and uninstall the software.

However, when you attempt to uninstall software when starting Windows in Safe Mode you will get an error saying the MSI Server service is not running.

To resolve type the following in a command prompt:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service"

net start msiserver

After running these commands you should be able to uninstall software.
