What Is The 0x80040702 Error?

In order to fix this error, there are certain steps you must take. Here’s what you need to do:

Steps To Fix The 0x80040702 Error

Step 1 – Replace Missing DLL Files

It’s often the case that Windows will be unable to read the files it needs to run the installation for your PC, and will just throw up the 0x80040702 error because it cannot find many DLL files. Fortunately, you can fix this pretty easily:

1) Note down the DLL file that your computer is missing

2) Click Start and then on Search

3) Search for the filename that’s missing. If a file appears, copy it into the c:\Windows\System32 folder

4) If there are no results, then click on Dll-Files.com and search for the file that’s missing

5) Download the DLL file from Dll-Files.com and then place it in the c:\Windows\System32 folder

6) Start the intallation again

This should solve the problem but if it does not, then proceed to steps 2, 3 & 4:

Step 2 – Clean Out Leftover Entries

If you are getting the error from trying to reinstall or modify an installation, then you might need to clean out any leftover entries from previous installs. This is a problem which is actually very easy to fix:

1) Scan through the registry with this registry cleaner to remove any leftover settings

2) Click on Start > My Computer

3) Browse to C:\Program Files\<Program Name> & Delete all the files

4) Restart your PC

5) Restart the installation

This will help your computer to run smoother and install the program you need, without having any problems from leftover files from a previous installation. Sometimes, uninstalling a program can leave files which have certain permission settings, etc. This will remedy that problem… but if it does not work, then you should proceed to step 3:

Download This Antivirus Program

Getting viruses is a big deal for any computer, and is one of the primary causes of the 0x80040702 error.
