# \[Loader] Loader Does Not Open / Nothing Happens If the loader isn’t opening at all when you try to run it, here are the most likely causes: *** #### 1. Antivirus Is Corrupting or Blocking the File This is the **most common reason**. Some antivirus software (including Windows Defender) will silently **block or corrupt** the loader before it even launches. > Disable your antivirus completely before running the loader. *** #### 2. Missing Dependencies If required system dependencies are missing, the loader may fail to start. > Refer to the **Overview** and **Dependencies** sections to make sure everything is installed correctly. *** #### 3. Your ISP Might Be Blocking Access (Rare) In rare cases, your internet service provider may block connections to our infrastructure. > Use a **VPN** if you suspect your ISP is interfering. This can restore access immediately. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
