Windows Installer Error 1719

less than 1 minute read

Description:

The other day I ran into an issue with Windows Installer: “Error 1719. The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed.”

To Resolve:

  1. Try:
    Navigate to: HKLM:\System\CurrentControlSet\Services\MSIServer
    Change DisplayName value: C:\WINDOWS\SysWOW64\msiexec.exe /V
    Open PS as Admin and run: C:\WINDOWS\SysWOW64\msiexec.exe /regserver
    Restart-Computer -Force

  2. If that don’t work, open CMD as Admin and type each of these one by one (or create a batch file):

1
2
3
4
5

%windir%\system32\msiexec.exe /unregister
%windir%\syswow64\msiexec.exe /unregister
%windir%\system32\msiexec.exe /regserver
%windir%\syswow64\msiexec.exe /regserver
shutdown /r /f /t 00
