subject: How To Fix Window Installer Error 1706 Instantly [print this page] You may encounter Window Installer Error 1706 when you are installing a program. Installation may be ended prematurely or there may be a fatal error during the installation. Window Installer Error 1706 happens because Windows installer is unable launch the relevant source files for the setup of the application software that you are trying to install. Those files may be missing or corrupted. Normally the original MSI installation files will be cached in the 'C:winntInstaller' directory before installation is started.
The first step to fixing the 1706 error is to reinstall / install the "InstallShield" program onto your PC. This will update & install all the files & features needed to help your computer process the installation you want. This does not come as standard with Windows, meaning that if you're seeing errors caused by it - it's likely because there's a problem deep on your system somewhere. You should also ensure you that you click the "Setup.exe" program to initiate the installer, instead of "Setup.MSI". This will allow the installer to locally interact with the files, instead of having to work out where they are kept on your system.
The next step to fix error 1706 is to resolve problems that are inside the "registry" of your PC. The registry is a central database which stores information & settings which keep your PC running as smoothly as possible. This part of Windows is very important, but is also one of the biggest causes of problems for your system. The issue is that as Windows continually has to use the registry to store such vital pieces of information as your desktop wallpaper & latest emails, most of the time, Windows PCs will get confused with many of the files that this part of your system has - leading your PC to show a multitude of errors. To fix this, it's vital you use a "registry cleaner" program to fix any of the damaged or corrupt settings that are inside the registry of your PC.
