Error installing Zoom 10003 is a very rare occurrence that users sometimes encounter. It occurs only on computers and laptops running Windows. But on Mac OS and Linux it is not. Since the failure is quite rare, it is difficult to find information on the Internet on how to fix it. We have prepared a detailed article that includes the most effective methods of dealing with it. Using our tips, you will definitely install Zoom on your computer.

Decision

The most common reasons for the error are:

  • Viral activity in the system.
  • Excessive temporary and junk files.
  • The presence of incorrect entries in the registry.
  • Damage to system components.

To make it more convenient for you, we have divided the solution to the problem into several steps. Follow them to deal with all possible causes, and then install the program.

Step # 1: Scan the system

The first step is to check for viruses on your computer and get rid of them if necessary. Any modern antivirus is suitable for this task: Kaspersky, Eset 32, etc. If you already have it installed, then run the scan in it.

We will analyze the procedure using the example of Avast, which is distributed free of charge and does an excellent job of protecting your PC.

Instructions:

  1. Go to https://www.avast.ru/free-antivirus-download .
  2. Click on the “Free Download” button .
  3. Accept the download of the avast_free_antivirus_setup_online.exe file if the browser asks.
  4. Next, run it and wait for the program to initialize.
  5. In the lower left corner of the new window, uncheck all additional offers.
  6. Click Install .
  7. The process takes approximately one minute. When it finishes, the antivirus itself will start.
  8. In the new window, alternately click on the “Continue” and “Start first scan” buttons .
  9. In the main window of the program, click on the “Protection” tile , and then on “Scan for viruses” .
  10. Activate the “Full Scan” mode .

Anti-Virus will start scanning the system for virus threats. The speed of the procedure depends on the power of the computer, but on average it takes 10-30 minutes . It is advisable not to use any other programs at this time.

If any dangers are detected, Avast will automatically eliminate them.

Step # 2: clean your PC

Over time, the computer is “clogged” with a huge number of unused files: program cache, temporary data, “tails”, etc. Their excess negatively affects the work of Windows. The solution is cleaning. The CCleaner utility is perfect for these purposes .

  6. In the completion window, uncheck Show Release Notes .
  7. Click Launch CCleaner .
  8. The utility will immediately open, go to the “Standard cleaning” tab .
  9. In the subsection “Applications” find the browsers that you are using, and uncheck them all. This is how it looks for Google Chrome and Opera :
  10. Click on the “Analysis” button and wait for the system scan.
  11. Then click on “Cleanup” .

Let’s move on to the next step.

Step # 3: Optimize your registry

During long-term use of the computer, a lot of unnecessary entries appear in the Windows registry, for example, from remote programs. They also negatively affect the operation of the system as a whole. But with the help of CCleaner you can get rid of them:

  1. Go to the “Registry” tab .
  2. You do not need to change any options in it, immediately click “Search for problems” .
  3. When the “Fix Selected …” button becomes active, click on it.
  4. Click “Yes” in the new window.
  5. Save a backup copy of the registry in the suggested Documents directory . It will come in handy for recovery if something goes wrong (but this almost never happens).
  6. Now click on the “Fix Selected” button .
  7. Wait for the procedure to complete.
  8. Restart your PC

If as a result of this procedure the computer starts to work somehow differently, then go to the “Documents” directory , open the previously saved reg-file , click on the “Yes” button , complete the procedure and restart again.

 

Step # 4: Restore Windows Components

Now type the command into the command line:

sfc /scannow

To execute it press Enteron keyboard.

Step # 5: Install Zoom

  3. Navigate to the directory where you saved the ZoomInstaller.exe file .

Extreme measures

What should you do if error 10003 still persists? Most likely, its cause lies in serious damage to system data. In this case, there will be problems with other programs, their installation and use. The most effective and radical solution is Windows recovery. As a result, the system will roll back to the previous state when there was no problem. The corresponding option is located in the Control Panel .
