I have introduced the method 1 to solve the Windows Installer Error in my previous article. If the method doesn't help you here is another one. I would like to emphasis that there are basically 2 approaches to solve the problem, automatically or manually.To fix the Error automatically, you can choose to use a registry error fixer, like ErrorFix, which will be very convenient for average computer users. You can get the review for ErrorFix by clicking the link at the bottom of this article.

If you like to solve it manually, here is the method 2.

  Fix Windows Installer Error Method 2

For this second method, you should reinstall the Windows installer.Please follow the following steps.

1. start Run… type “cmd”, a command prompt will be opened

2. run the following commands one line by one line

attrib -r -s -h c:windowssystem32dllcache

These steps helps you to rename the existing msi.dll, msiexec.exe, and msihnd.dll files.

4. Download the latest update of Windows Installer for your Windows operating system from the Microsoft Download Center, then install it on your system and restart your computer. This method should rectify your solve the installer problem.

If you receive an error related to Windows Installer then you can resolve it either by re-registering the msiexec.exe file or by reinstalling the Windows Installer. However, please be careful while working with the registry and always make a backup before making any changes to it. If you are not familiar with or not confident in correcting the registry by yourself, you should try to use a error fixer. I strongly recommended ErrorFix to you as it is the best registry cleaner I have ever used.
