Error Code 21: This could mean the redistributable is outdated or corrupted

 

What Causes Error Code 21?

Sonar needs Microsoft’s Visual C++ 2015–2022 Redistributable (x64) to work correctly. If that thing’s broken or outdated, Sonar won’t start and will give Error Code 21.
 

How Do I Fix It?

You can resolve the error in one of two ways:

Repair the Existing Redistributable

  • Open Windows Settings
  • Go to Apps > Installed Appspci1.png
  • In the search bar, type: "redistributable"

  • Choose Repair and follow the prompts

  • Download the latest version of the 2015–2022 Redistributable (x64)
  • Run the installer and complete the setup
     

How Can I Prevent This Error in the Future?

To avoid this problem again, make sure Windows and all your software are up to date, and check for updates to the Microsoft Visual C++ Redistributable periodically.

 

GLHF!
