JSI Tip 4808. Error 1719, 'The Windows Installer Service could not be accessed'?

When you run an MSI package, you receive:

Error 1719. The Windows Installer Service could not be accessed. You may be running in Safe mode or Windows Installer may not be correctly installed.

To fix this problem:

1. Use the Registry Editor to navigate to:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSIServer

2. Double-click the ImagePath Value Name, a REG_EXPAND_SZ data type, and verify that the data string is %SystemRoot%System32msiexec.exe /V, where %SystemRoot% is the location of your OS, like C:Winnt or C:Windows.

3. Shutdown and restart in Safe mode by pressing F8 when the boot menu displays.

4. After you log on, run msiexec /regserver.

5. Shutdown and restart normally.
