i've installed camoufox as in website says, but i got this issue with my first code

playwright._impl._errors.Error: BrowserType.launch: Failed to launch firefox because executable doesn't exist at C:\Users\Admin\AppData\Local\camoufox\camoufox\Cache\camoufox.exe

You have to run camoufox fetch.

Next time RTFM https://camoufox.com/python/installation/

This is actually an issue... - For whatever reason on Windows 11, it acts like it's downloading and extracting to the correct path ...\AppData\Local\camoufox\camoufox\Cache, but the path doesn't exist past Local after "successful install". I thought maybe it was a third-party library issue at first, but can't even run camoufox test:

camoufox fetch

When I run camoufox path, it thinks the install location is valid :

camoufox path
C:\Users\***\AppData\Local\camoufox\camoufox\Cache

I played around with it for a bit:

Switching to Admin prompt did nothing
Forcing folder creation in AppData did nothing
Changing to the C: drive and then running did nothing
I did change the INSTALL_DIR to my current working dir and the download was successful. So I don't think it has anything to do with the download process.

Not exactly sure what Windows is doing under the hood, but it seems to be faking out the mkdir and extraction calls. Let me know how I can help debug further.

I've determined that it's somehow sandboxing C:\Users\***\AppData\Local\ to C:\Users\***\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\LocalCache

Not entirely sure why or how to give camoufox the new dest path.

UPDATE: For anyone stuck in this similar situation, the current workaround is to uninstall python from the Microsoft Store and install directly from python's website. Hope this helps!

Thanks for the info about the path. I found another workaround, even with Python from MS Store. If you follow the path: C:\Users*\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\LocalCache, then go to Local, you will see the folder "camoufox". Copy the folder and paste it into this directory: C:\Users*\AppData\Local. This way the browser will start. The only inconvenience is if there is an update - you'll have to manually update your pasted folder as well. But it works at least

Here is a complete workaround and fix. Uninstall all versions of Python and install Python 314. Start > Edit Environment Variables For Your Account > Environment Variables... > Click on Path under User Variables for 'YourDrive/PC' > New > Type the following (Ensure your drive name/PC name replaces the placeholder; C:\Users\Placeholder\AppData\Roaming\Python\Python314\Scripts > Press OK to all options > Start a new CMD/Powershell > Type; camoufox fetch
