Use the following command to update to the latest version:

```auto
.\python.exe -m pip install --upgrade comfyui-frontend-package

```

I ran this command inside “python\_embeded” folder and fixed the issue with the error message in my case

I am a Comfyi Beginner - have the same issue. But I realy do´nt know, where the “python\_embeded” folder is.  
Some weeks ago I ha an issue with an installation because he didnt except too long names/ filepathes. Following an instruction I moved the whole File structure from  
H:\ComfyUI\_windows\_portable\ComfyUI  
to  
H:\ComfyUI\ and all worked fine

Now I get this message:

 ![image](https://canada1.discourse-cdn.com/flex009/uploads/comfyui1/original/1X/ba99ddebc9bcf447fdfd41a8fcd2b69e64e3bfc5.png)  
And I need to make the stuff in an not existing “phyton\_embeded” folder …

Do you know how to fix this?  
Thanks in advance

@le_horge The python\_embeded folder is located in H:\ComfyUI\_windows\_portable. You should just relocate everything to its original location and then run the command inside python\_embeded.

Thanks a ton dude! Out of nowhere the previews weren’t showing, even updating everything didn’t fix it, but this one did.

So this was posted on Desktop Feedback.

Can I presume that Comfyui-desktop has a “python\_embeded” folder?  
Because I can’t find it.

I’m beginner, but If you run desktop like I do, you should have python installed in your system, so no need for python\_embeded folder. I run all the commands in console simply as python.exe …

Like here:

D:\_AI\ComfyUI\>python.exe -m pip install --upgrade comfyui-frontend-package

and it installed the latest version. When I run it for the second time it showed

Requirement already satisfied: comfyui-frontend-package in c:\users\XXX\appdata\local\programs\python\python312\lib\site-packages (1.30.3)

Unfortunatelly it didn’t help with the front-end issue. After restart of the app and attempt to install missing nodes over Manager it sill writes:

[ComfyUI-Manager] Skipped fixing the ‘comfyui-frontend-package’ dependency because the ComfyUI is outdated.

Is there something else I’m missing? The ComfyUI should be uptodate. The Manager doesn’t show any update option.

I don’t really worry about updating comfy anymore. I download the latest portable, move over my models and nodes, fix the ones that don’t start, and I’m back in business pretty quickly.
