Internet Explorer automatically changes the extension for JAR files to ZIP. What should I do?

If you're trying to install or upgrate YouTrack with the JAR distribution and your web browser renames the file by changing the extension from .jar to .zip, you don't have to do anything special. The contents of the file are not affected.

  1. Change the extension back to .jar
  2. Proceed with the installation or upgrade.
