Error while installing everest

[civic walrus]

It died, a brutal death, literally

just installed olympus and tried to install everest and i got an error saying "Mini installer died a brutal death, ask the celeste discord server for assistance"

here are the logs.

ok logs failed to attach to discord

[civic walrus]

there was another log, but it was empty, literally nothing is written within it

[civic walrus]

and was causing that error so, it was not included

System.TypeInitializationException: The type initializer for 'MonoMod.MonoModRules' threw an exception.
---> System.Exception: This version of Celeste is already modded. You need a clean install of Celeste to mod it.

the only reasonable cause for this is that the vanilla copy in orig is not actually vanilla

is there a MMHOOK_Celeste.dll in orig

[civic walrus]

what is orig? is that a file? (sorry im slow)

[scarlet warren]

orig is where a vanilla copy of the game is backed up to before installing everest

it's in celeste's game files

it's a folder

[civic walrus]

how do i get to celeste's folders

...is celeste not here 💀 i just installed it i swear

[scarlet warren]

no, it is

i'm saying that the vanilla copy in orig which you're restoring is not actually vanilla, but everest

which is why it's saying "hey you gave me a modded copy of celeste"

right click celeste > properties > installed files > browse

then open the folder named orig and tell me whether MMHOOK_Celeste.dll is there

[civic walrus]

alright! give me 1 minute

nope

there is no MMHOOK_Celeste.dll

[civic walrus]

yeah just double checked and tried searching, there is no MMHOOK_Celeste.dll

[scarlet warren]

hm

what is inside then

[civic walrus]

the folder names?

theres like mono cecil

net corifier

nvm i can take a screenshot

[scarlet warren]

okay yeah this copy has definitely been modded

[civic walrus]

do i delete and reinstall celeste?

[scarlet warren]

so basically verify game files, delete the orig folder and reinstall everest

Steam Instructions
Epic Games Store Instructions
If you have Everest installed, you will need to reinstall it after verifying.

[civic walrus]

oh okay

okay i verified game files (smth went wrong with 6 files and idk what steam did with them)

deleted the orig file

currently downloading everest

hey it worked

[scarlet warren]

the fact 6 files failed to validate is normal

everest injects itself into celeste to make it work

doing so changes the contents of the executable, which makes it no longer vanilla

verifying game files checks whether the files on your computer are exactly the same on steam's servers

and since the files you get when you install celeste do not have everest, steam thinks the files failed validation (despite them still being "fine")

verifying game files is basically just "are my game files identical compared to what steam got?"

[civic walrus]

you're the first person thats nice enough to explain the problem and the solution, rather than saying "just do as i say and the game will work" 🥹 ty

the game is working just fine now

much appreciated

[scarlet warren]

yea, i just wanted to explain

since it's something else when you wonder "ok but what does this actually do"

[civic walrus]

yeaaaah

[scarlet warren]

and something else when you actually understand what you're doing

since you can see that i kinda know what im talking about

[civic walrus]

if only all customer support agents were like you

well ty! is there a way i can close this now

[scarlet warren]

oh i just marked it as resolved anyway
