How to Fix “Updating Component Registration” Delay During MSI Installation

Common Causes of “Updating Component Registration” Hang

Each time you install an MSI, the installation goes through the "Updating component registration" stage as part of the Windows Installer process.

During this stage, Windows Installer executes a number of actions built into the MSI.

Most commonly, this delay happens during the “ProcessComponents” and “InstallFiles” actions, which can take longer to complete if the MSI contains many files or numerous registry entries.

As mentioned, there are steps you can take to avoid or resolve this issue.

Step-by-Step Solutions to Fix “Updating Component Registration” Issues

First, make sure your system isn’t overwhelmed and has enough resources to complete an installation. While it might seem trivial to consider an installation package as "resource consuming", there are actually many background processes happening during installation.

Closing unnecessary applications and freeing up disk space can help Windows Installer run more smoothly.

If that doesn't work, try cleaning up the Windows Installer cache folder. This folder is located in C:\Windows\Installer and stores temporary files needed for installations or reinstallations.

Deleting files from this folder can sometimes resolve issues that can appear during the installation.

Although rare, the Windows Installer service itself might be corrupted.

Remember, the Windows Installer service is responsible for actually installing the MSI packages, which are databases that tell the Windows Installer what actions to perform on your system.

You can attempt to repair the Windows Installer service using these simple commands:

msiexec /unregister
msiexec /regserver

Of course, we can never rule out the MSI package itself as the cause. If you suspect the MSI is corrupted, try downloading the installer again from a trusted source and then retry the installation.
