A customer recently contacted me due to a problem they were experiencing while trying to install the .NET Framework 2.0 on the x64 version of Windows Server 2003. I took a look at the verbose log file for this scenario and saw the following error:

I was so excited after searching for weeks trying to find a fix for these Windows Installer problems that I threw away my notes and just kept the fix stored in a txt file.

Usually when I see error 1719, I recommend that the user try to repair the Windows Installer service. However, in this case, that didn't seem to help, and I had to refer this customer to the Microsoft technical support team for further assistance.

Our technical support team looked at this scenario in more detail and found that there was an additional set of steps needed to repair the Windows Installer service on a 64-bit OS.

Here is a complete set of steps that should allow you to repair the Windows Installer service on a 64-bit OS:

1. Click on the Start menu, choose Run, type cmd and click OK
2. Run this command: %windir%system32msiexec.exe /unregister
3. Run this command: %windir%syswow64msiexec.exe /unregister
4. Run this command: %windir%system32msiexec.exe /regserver
5. Run this command: %windir%syswow64msiexec.exe /regserver
6. Restart the computer

After executing all of the above steps, you can try to re-run the failing setup and hopefully get better results.

Windows Installer is a core service which manages installations of everything in Windows including apps, features, and many other things. If for some reason, it breaks, you will be stuck with new installations and even upgrades of apps. In this post, we will share a list of error codes – and their solution, some pointing to our existing solution – and how to solve them.

Windows Installer not working

Run Program Install & Uninstall Troubleshooter

The first thing we would suggest is to run the Program Install and Uninstall Troubleshooter to repair issues that block program installation or removal because of corrupted registry keys. This program will fix corrupted registry keys on 64-bit operating systems, which control the update data, problems that prevent existing programs from being completely uninstalled or updated, and problems that block you from uninstalling a program through Add or Remove Programs (or Programs and Features) in Control Panel

Start the Windows Installer Service

Windows 7 Installer Service Not Correctly Installed

In the Run prompt, type MSIExec, and then press Enter.

If you get the Windows Installer window which tells you everything about MSIExec, then it’s all good.

If you get an error, you might have to start it manually. Free code 128 font for excel.

Right-click on the taskbar, and select Task Manager. Switch to Services, and look for msiserver. Start it.

You can also run services.msc to open Windows Services and go to Windows Installer, and restart it.

This usually happens if the Windows Installer Engine is corrupted, installed incorrectly, or disabled. You will need to fix either the corruption or fix the configuration or enable it. The linked post also solves the issue where the Windows Installer service could not start, and gives the message as Error 5, Access is denied.

If the Windows Installer package faces unstable network access during the uninstallation or installation process, sometimes, the error might appear if you fail to complete the process successfully. The error message might go like “There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.”

Usually, the Windows Installer or msiexec.exe runs in the background. You can check in the Task Manager under the list of processes that are running. However, if you see it constantly running, and the installer keeps coming in front time to time, it means it is stuck. It is possible that an installation is not able to complete, and this happens as a result.

Installation Package could not be opened

If you are not able to install a software which you just downloaded from the internet, and it keeps throwing error message “Installation package could not be opened”, then its probably a security issue. Windows many a time blocks application you download from the internet as it does not trust them. You may have to unblock it or disable your antivirus to fix it.

Re-register Windows Installer service

If nothing works, the best option in our experience is to re-register the Windows Installer service. The reason why it works great because it fixes registry issues as well, and gets the basic settings ready again.
