Common Problems

We can't continue because there's a file named "Battle.net" in your ProgramData folder (C:\ProgramData\Battle.net). Please delete that file and try again.

The Battle.net desktop app installer can't continue because it detected a file already named Battle.net. If you created this file manually, it may cause installation or patching issues.

Delete the folder named "Battle.net" at the file path specified in the error dialog. This should allow you to restart the installation and complete it normally.
Delete the Battle.net Tools folder to automatically rebuild outdated or corrupt files.
