Q1: Please Choose Your Malwarebytes Product:

Can't install antivirus

Malwarebytes is a top-notch anti-malware software that brilliantly detects all the malicious content on your computer. However, sometimes it might create issues in the installation process, and an error message appears as "An error occurred during installation." Restart your computer when this issue arises. If the problem persists, look for other troubleshooting methods.


  • Leftovers of previously installed software. 
  • The System may have corrupted files.

Solution 1: Check the Internet Connection

An unstable internet connection may put your computer in trouble, so don't let the applications and programs be installed. Hence, checking the internet connection is necessary. Follow the steps below.

  1. Close all the downloading programs except Malwarebytes.
  2. Remove all the other devices connected to your router.
  3. It's better to use a cable connection in place of a wireless connection.
  4. Disconnect your router for a few minutes to let the connection reset. 

Solution 2: Temporarily Turn Off Your Antivirus and Firewall

The antivirus software and firewall may prevent the installation of Malwarebytes on your computer. But a temporary turn-off of antivirus and firewall will solve the problem. Otherwise, you can Clean and Reboot your computer. 

Solution 3: Remove Unnecessary Files

An installation error might occur if your drive doesn't have enough space to install new apps and programs. Hence, remove the files you don't need or use. Usually, video files take up a lot of space on your drive. Delete these files and move them to the recycle bin, empty recycle bin, and try again.
