How to Resolve Installer Error 1719

To resolve this problem, you must register the Windows Installer Service.

If you are using Windows Xp:

1. Click Start

2. Click Run

3. Enter the following command (as shown in the image below) and then click OK.

msiexec /regserver

If the command above produces a path not found error, enter the following command:

 C:Windows\system32\msiexec.exe /regserver

If you are using Windows Vista or Windows 7

1. click Start and then type CMD in the Start Search box.
   Right-click the cmd.exe in the program list that is displayed, and click “Run as Administrator”.
2.  Type the following commands in the Command Prompt window one by one and press Enter to execute them:
   > msiexec /unregister
   > msiexec /regserver
   > net stop msiserver
   > net start msiserver

The last 2 commands stops the Windows Installer and then restarts it. The first 2 resets the registry of Windows Installer Package in the Windows registry.ie. Stop the msi server and then start it again. Unregister msi executable and register it again. You can avoid the last 2 entries, if you reboot your computer after the execution of first 2 commands.

In Windows 7 64 bit, you might want to do the following,

1. Start, then Run, then type regedit
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CURRENT CONTROL SET\SERVICES\MSIserver\WOW64
3. Right click on WOW64, then select Modify
4. Set Value Data to 0 (if is set to 1) and Base should be Hexadecimal
5. Close the Registry Editor
6. Start, type CMD in the search bar.
7. In the Command Prompt, Type net stop msiserver Enter and Type net start msiserver and then Enter. To execute both the command.

If that did not work, you want to register it first,

1. click Start, click Run, type C:\Windows\Syswow64\Msiexec /regserver in the Open box, and then click OK.

Note: Or you can restart the PC for changes to take effect without doing steps 6 and 7.

If doing that in normal mode did not resolve the problem, try doing that in safe mode. Read this article on how to start windows in safe mode, if you are not sure.
