Windows Installer will not work when booted into Safe Mode, this means that programs cannot be installed or uninstalled in safe mode however we can make Windows Installer work under safe mode, you need to create a registry entry for the specific version of safe mode you are logged in to.
Safe mode
Add the registry key by entering the following into command prompt:
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.
C:\Windows\system32>REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer” /VE /T REG_SZ /F /D “Service”
(c) 2013 Microsoft Corporation. All rights reserved.
C:\Windows\system32>REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer” /VE /T REG_SZ /F /D “Service”
Then start the installer service with the following command:
C:\Windows\system32>net start msiserver
Safe mode with networking
Add the registry key by entering the following into command prompt:
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.
C:\Windows\system32>REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer” /VE /T REG_SZ /F /D “Service”
(c) 2013 Microsoft Corporation. All rights reserved.
C:\Windows\system32>REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer” /VE /T REG_SZ /F /D “Service”
Then start the installer service with the following command:
C:\Windows\system32>net start msiserver
That’s it, you’re now free to uninstall or install some stuff, although this doesn’t guarantee a successful installation or uninstallation.
