Windows Installer will not work under Safe Mode, this means that programs cannot be installed or uninstalled in Safe Mode without giving a specific command using msiexec in command prompt. To make Windows Installer work under Safe Mode, you need to create a registry entry for every type of safe mode you are logged in to.
1. Safe Mode: Type this in a command prompt
Reg ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer” /VE /T REG_SZ /F /D “Service” And then net start msiserver This will start Windows Installer Service.
2. Safe Mode with Networking:
Reg ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer” /VE /T REG_SZ /F /D “Service”
