The error is shown when Windows cannot read the registry settings it requires to run the installation application.
Every time you install a program onto Windows, 100's of files & settings are placed into various parts of your computer, including the "registry".
The registry is a large database that all Windows computers use to keep the settings & information they require to run, allowing your PC to keep running as smoothly and effectively as possible.
Even though the registry is one of the most important parts of each Windows PC, it's continually causing a large number of problems for your system - as it's either being corrupted or is made unreadable.
If you want to fix the 1402 error, you need to fix the registry.
How To Fix The 1402 Error The error you're seeing is basically caused by Windows being unable to read its registry settings properly, meaning that if you want to resolve the problem you're seeing, you first need to ensure the registry database of your PC is working correctly, as well as any further problems which may be leading the 1402 issue to show.
The way to fix the problem is to first try and run the installation under a different user profile.
User profiles are used by Windows for a variety of reasons - from helping your computer run with customized options to setting a series of permissions for your PC.
Although the 1402 error you're seeing is commonly caused by registry issues, it's likely that your user profile simply isn't permitted to install the files & settings that you need.
To resolve this, you should either perform the installation with a different user profile, or create a new profile entirely.
You should also use a registry cleaner tool to fix any potential problems inside the registry database of your PC.
These are tools which work to scan through the registry database of your PC and get rid of any of the files / settings which may be causing issues for your PC.
Considering the registry is the main cause of the 1402 errors on your computer, it's highly recommended that you resolve any of the potential problems the system has by using a registry cleaner program to scan through your PC and fix the errors it finds.
