Make a new file on your PC wherever you want, name it whatever, and install Dotnet into it, as well as the depot downloader folder with all it's contents

https://dotnet.microsoft.com/download/dotnet-core Download this, I downloaded 5.0 but some say 3.1 is ideal, it's up to you what you try

https://github.com/SteamRE/DepotDownloader/releases Download DepotDownloader.zip, and unzip it into the folder

Properly install dotnet core

Open https://steamdb.info/depot/1051201/manifests/, copy a "MANIFESTID" (These correspond with versions of the game, the lower on the list are older games)

Open the folder inside of the folder you created (It should contain many .dll files)

Click at the top of your file explorer menu where it shows what files you are looking at (It should let you type there)

Type in "cmd" which should oppen the command prompt of that directory

Type inside the command prompt the following: dotnet DepotDownloader.dll -app 1051200 -depot 1051201 -manifest [Paste MANIFESTID] -username [Your steam username] -password [Your Steam password]

If you have 2 factor authentication enabled on Steam then you will need to provide the code it sends your phone, it will ask for that if you have it

Let it install Once installed, open your DepotDownloader folder, go into Depot folder

There will be a folder named some number, open it, then open the next folder with a number on it

I am unable to test this currently, but do NOT open trover.exe until finishing EVERY step, as we don't know if that will do something to the file

You should be able to see some folders named ..DepotDownloader, trover_data, and a file, trover.exe

On your desktop, or some safe memorable location on your computer, create a folder and name it whatever you'd like (OldPatchTrover may work for you)

Inside of that folder, make a new folder and name it the version you are trying to run, if you don't know what that version is, name it anything

Copy everything except .DepotDownloader and paste it into your new folder

Create a text document in that folder and name it steam_appid.txt

Inside of the text document, paste this number: 1051200

Create a new folder, name it something like TroverBackup.

In your file directory, access Steam files, open your Trover folder, select all the files, right click and select cut

In your TroverBackup folder, paste those files (Feel free to delete this if you don't plan to use them, as it would be just a waste of space)

In your OldPatchTrover folder (The one that you used DepotDownloader with) Cut all the files and folders inside of that, and paste them inside of the Steam Trover folder

Open Steam and launch Trover through Steam, and it should be running on the earliest patch.
