Have you ever experienced problems when installing Java or the likes on your computer? If yes, then you have faced one popular issue, the so-called 1721 Windows Installer error. The fundamental cause of this error is your PC’s inability to read the different programs or files that are required to run the installation program, thus, hindering the installation from proceeding. It’s neccessary for you to fix this error by solving any problem that may prevent you from installing your software and identify any problem occuring to your Windows system.
The 1721 Windows error will show like this:
* Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personal or package vendor.
The cause of this error is because your PC cannot read the files / programs it requires in order to complete the installation on your system.
Every time you install a program on your PC, a large number of files are basically copied from the installation program to your hard drive. This means that if you are trying to install a program, you first need to make sure the installation file is complete & operational, as well as fixing any errors your system has inside.
The way to fix this error is to first “unregister” and then “re-register” the installer on your system. This will act like a re-install for the Windows installer, allowing your computer to properly read all the files & settings it requires to use again (because Windows Installer is a crucial part of Windows, it’s impossible to remove it from your PC completely – so you need to re-register it to make sure that it’s working correctly). After that, you should then use the “Windows Installer Cleanup Utility” – which is a piece of software you can get from the Microsoft website which will basically repair any of the problems that your Windows Installer program may have. This is highly recommended, as it will basically make your computer run much more reliably when installing a piece of software.
If you use the method above and find it does not work, you should then look to use what’s known as a “registry cleaner” on your system to try and fix any potential errors that may be inside the registry. A registry cleaner is a software tool that will scan through your computer and repair a large number of files & options that could be damaged / corrupt on your system, and help resolve a lot of different errors on your PC. It’s often the case that the 1721 error will be caused by your computer being unable to read the various registry settings that are needed from the installation folder, making it necessary to clean out the registry on your computer with one of these registry tools. This is highly recommended as it could fix a large number of problems your system may have.
