Windows 7 - Windows installer Error 1719

Hear Hear! I am also very grateful to Flavius. I had been trying for several weeks to install Office 2010 and Flavius' solution sorted it withn a few minutes.

I have tried all of the fixes listed here and still have the problem. I do not have a Windows Installer listed in the Services. Any help would be appreciated. Windows 7 Pro 32 Bit

Hello everyone,

I had the exact same problem where any time I tried to install a program, I got the error message "windows installer service could not be accessed", but none of the fixes I found online worked.

After tons of trial and error and banging against the wall, here's how I fixed it:

1. I went into the windows registry to the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msiserver] path.

2. I changed the ImagePath value from "%SystemRoot%\system32\msiexec /V" to "C:\Windows\system32\msiexec /V"

3. I went into my windows services (services.msc) and stopped and started the Windows Installer Service. I also set it to start automatically.

4. I rebooted my computer.

5. Problem solved!

Essentially, for some reason or another, I had to hard-wire the path to the msiexec executable to the C:\ drive instead of using the dynamic %SystemRoot% variable, and that fixed it for me.
