I can’t seem to be able to get this to work. After downloading I run the setup.bat through Git CMD and it gives back the following error:
$ ./setup.bat

How do I fix this?
hi @Casper_AP ,
I have tried this with error loging and the error is
<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>
Looking at you initial entry you have not correctly set your path
If you type “pwd” and you will probably find you are at C:\ the root
under normal conditions users applications cannot make files there
type
*Make a directory path /c/Users/Owner/source/repos
The “Owner” is replaced with your username.
or
*Make a directory path C:\Users\Owner\source\repos*
The “Owner” is replaced with your username.
Using Windows File Explorer
either way you need to
$ cd /c/Users/Owner/source/repos
git clone into the directory as the readme explains
then run ./setup.bat to pull down dependencies
This error also ours when your path is long paths over 25 character is the often reason for an error
Hello @Jimbohalo10 ,
Thank you for fast response. Yesterday I downloaded the files and copied them over to my D drive because my C is quite full. I am not sure if I did the correct thing according to your response but this is what I tried today: I ran git CMD in C:\Users\User\source\repos (it already existed) Then downloaded the ue5Lgpu511 folder into here. Right clicked on it and used git BASH to run ./setup.bat Unfortunately the same error occurred. If I run setup.bat through the git CMD and cd to the folder, I get Aborting dependency updating due to unknown failure(s).
I hope it’s clear what I’m trying to say, and thank you for your time.
answer in post further on
Hello,
I copied the git folder to D:\Program Files\Git and ran it. Then used it on the ue5Lgpu511 folder on the D drive. The same error occurred.
I don’t really understand why you are saying the drive says its missing? The error states it failed to download because the archive was using an unsupported compression method?
I wish the old installation method was back 
Hi @Casper_AP ,
For the old method, for 5.1.1, its always been there.
Go into Epic Games Launcher → Library
see EpicLauncher download 5.1.1
on drive D:
The final version binary of 5.1 was infact 5.1.1
the binary files which are used to replace the original comes form
here.

You just go to D:\Program Files\Epic Games\UE_5.1 and extract unzip the archive on top of them. Its a zip file does not require Git.

Somehow I completely missed that, probably because I was looking for 5.3.0 at first. Thank you for your time.

It’s been a whole day since I am baking lights on CPU very bad results. But I come across this post and used files you have provided; I must say it’s literally took 3 minutes baking same scene (on GPU) and much nicer results Thanks, you saved my day. Now I can die in peace.

Hi @nickday,
Looking at the error log this is not errors from my repository code. Many people have used this 5.3 LGPU code. The code from LGPU 5.1 Cannot be mixed. I have hand code 5.3 code to work with LGPU at
LGPU 5.3 Git repo
The error suggest a missing file CookMeta.h
Line 42 of CookOnTheFlyServer.cpp
My code have the following at line 42 CookPackageSplitter.h
![noLGPU53code|610x356, 50%]
(upload://dMXRdAGMYj4YLcFzE7E3JWrfkNe.png)
I therefore suggest you archive your current code and use the repository link above.
If you want the original 5.1 binary got to post
