Go get it here: Moddb.com
Thanks to Stachelhaut for his updated Veles face texture, it looks amazing!
Thanks to Stachelhaut and zlostnypopolnik for testing and feedback of the Duty quest fork
With this release I am officially retiring from STALKER modding including LA. It has been a fun 14 years or so! As mentioned in my previous article, I will still continue to monitor this page and answer any questions though.
Good hunting stalkers!

With the announcement of STALKER 2 I see more traffic here, so I wanted to give a quick guideline on the different LA DC versions.
There is a new version of LA out (DC Extended). Check out the details below for more information.
This news post is to be used more as a resource for LA updates from the RU team/modders.
STALKER LOST ALPHA: REVISTED (LAR), is formally known as "LB's Comp." LAR combines ALL of my previous mimimod/comp updates along with the revised Duty...

How do I fix this?
You did not fully read the instructions or patch notes... LAR is not compatible with PRM (that error only appears when using PRM with LAR), it is mentioned multiple times.
Hey it's my first time in this and i'm gettin a error in the .exe (0xc000007b)
i tried some fixes and nothing
That error is not really helpful... and what "fixes" did you try?
First thing, are you playing DC/LAR or DCE? If DCE, I cannot help. If using DC/LAR are you using the newest launcher included in LAR?
i tried changing some windows configurations, installing the visuals and directx, reinstalling and downloading the launcher you mention but nothing
Btw i downloaded the DC 1.4007
This is not a LA related issue ...
You have to install Visual C ++ and update your DirectX Runtime , reboot and you should be good to go .
So i installed the Visual and updated directx and nothing :/ when i choose start new game the error keeps
Can you give a bit more info ?
System specs ?
And just a headsup: this is a standalone mod , you don't need the original game for this
Procesador 11th Gen Intel(R) Core(TM) i3-1115G4 @ 3.00GHz 2.90 GHz
RAM: 8GB
And like i said i already installed visuals, updated directx and when i open the configurator and select launch game i get the error 0xc00007b but when i select start new game i can choose the language and the difficulty, after that i get the same error
And Microsoft's .Net software ?
I still think you are not using the updated launcher, or something else is not installed correctly... In any case, please see the instructions on how to bypass the launcher in my patch notes. If there is an error on startup that way, you installed incorrectly.
