# Browser Driver Auto-Download Issue After Upgrading to Leapwork 2025.3.0

**Overview**  
With the **Leapwork 2025.3.0** release, **Selenium Manager** has been upgraded to **version 4.34**, introducing enhanced browser and driver management capabilities. In some cases, after upgrading, **browser drivers (ChromeDriver or EdgeDriver)** may fail to auto-download. This is typically caused by outdated driver files remaining in the Leapwork installation directory, which prevent Selenium Manager from fetching the latest versions.

**Symptoms**  
1. Chrome or Edge browser sessions fail to start.  
2. The expected auto-download of drivers does not occur after the upgrade.  
3. Execution errors indicating missing or incompatible drivers.

**Cause**  
Outdated `chromedriver.exe` and `msedgedriver.exe` files from previous versions may still exist in the installation directory. These files override Selenium Manager’s automatic driver management functionality introduced in version 4.34.

**Resolution**  
To ensure Selenium Manager downloads the correct drivers automatically, follow these steps:

**1. Close Leapwork Studio** (and Agent, if applicable).  
**2. Navigate to the installation directory:**  
For Studio:
```
C:\Program Files\Leapwork\Studio
```
For Agent:
```
C:\Program Files\Leapwork\Agent
```
**3. (Optional) Back up your existing driver files:**  
`chromedriver.exe`  
`msedgedriver.exe`  
**4. Delete both driver files (`chromedriver.exe` and `msedgedriver.exe`) from the folder.**  
**5. Restart Leapwork Studio.**  
**6. Retry your execution.**

**Expected Outcome**  
Selenium Manager will automatically download the correct and up-to-date drivers at the following location:
```
C:\Users\<Username>\.cache\selenium
```

**Additional Information**  
This issue only occurs after upgrading from earlier Leapwork versions that bundled static driver files. The new Selenium Manager version ensures automatic and version-matched driver management for Chrome and Edge browsers. Manual driver management is no longer required once the outdated binaries are removed.
