Windows installation issues

Some error messages you may encounter when installing Anki:

• "Error opening file for writing"
• "Windows protected your PC"

Please also see startup issues.

"Error opening file for writing"

If closing Anki and your browser does not help, please try restarting your computer, then running the installer again.

"Windows protected your PC"

When a new Anki version is released, Windows may display a scary-looking message until it has seen enough people using the new version. To be able to proceed with app installation, please use Run anyway.

Antivirus programs may sometimes also report a false positive.
