# \[Loader] This app can't run on your PC

### Loader File Is Corrupted?

If you're seeing an error or the loader isn't functioning properly after download, your loader file has most likely been **corrupted**. You'll need to **re-download it**.

***

#### 🔍 Common Causes of Corruption

* ❌ **Antivirus software** interfering with the file
* ⚙️ **Virtualization-Based Security (VBS)** or **Hyper-V** still enabled
* 🚫 **Disallowed software** like reverse engineering/debugging tools running
* 🌐 **Browser blocking the file** (especially Chrome)

***

#### 💡 Chrome Download Block Fix

If Chrome is blocking the loader as a “suspicious file,” here’s how to fix it:

1. After downloading, press `**CTRL + J**` to open the **Downloads** panel.
2. Click the `⋮` (three dots) next to the blocked file.
3. Choose **“Keep”** or **“Keep unsafe file”**.

> 🔐 Make sure to disable antivirus and confirm VBS/Hyper-V is off before running the loader. See the **VBS & Hyper-V** section for guidance.
