How to Fix the 0x80040702 Error on Windows

The 0 × 80040702 error is common on computers on which you are trying to install a game or piece of software. The error will show for a variety of different reasons, but is almost always shown when you are installing something on your PC. There are several causes of this problem and several ways to fix it, depending on the cause. Here's what you need to do to fix it ...

The largest reason why this error appears is because of missing DLL files on your system. To fix this, you must first see if your PC has any of the missing DLL files on your PC and if it does, then put that file in the right place. To do this, click on Start> Search. Then search for the filename the installer claims is missing. If any results come up, then copy the file into the C: Windows System32 folder of your PC. If there are not any files with that name on your system, you should search for " + download "on Google, download the file and put it into the C: Windows System 32 folder.

If that method does not resolve the issue, you should then perform a clean out of any leftover settings that previous installs may have left. To do this, browse to C: Program Files and delete all the files inside that folder, clean out your PC with a registry cleaner and restart your PC. This should stop the error if it appears when you try to perform an upgrade, repair or reinstall of your software.

If these do not work, you might have a virus infecting the files or settings the program needs to install. To combat this problem, you should download an antivirus program and then install it on your PC, allowing it to scan your system. It will find and remove all the infections on your computer, which may stop the error from appearing.

Finally, you should also try to clean out your entire system with a registry cleaner. this will scan through the registry database (where all the settings are kept for Windows) and will remove any of the damaged or corrupt files that are inside there. Using this tool will boost you PC's speed and also make Windows much more stable ... and should stop the 0x80040702 error as well.
