Fixing MSI.dll Errors

Msi.dll, which stands for "Microsoft Installer Dynamic Link Library", is an integral component of the Microsoft Installer service. Without this important DLL file, you will be unable to install software on your computer that relies on the Microsoft Installer. Although you may occasionally encounter msi.dll errors, these by no means indicate that msi.dll is a malicious software program. Deleting or renaming msi.dll could cause serious damage to your system, and as such, it is both a hidden file and a hidden process.

Understanding and resolving msi.dll errors

When you try to install certain software products, you may receive the following error message:

According to a Microsoft Knowledge Base article discussing this error, this problem is typically caused by corrupt Microsoft Installer files on your hard drive.

If you are running Windows NT 4.0 or Windows 2000, download the updated version of Windows Installer 2.0 here. Keeping msi.dll up-to-date

Keeping msi.dll up-to-date

Because msi.dll is a Microsoft Windows system file, Microsoft takes responsibility for maintenance and updates. You should run Windows Update and ensure you have the most up-to-date version of all Microsoft Windows files, including msi.dll. To check Windows Update for the latest software for your computer, navigate to Microsoft's Windows Update site using Internet Explorer 5.0 or later.
