Reverts patches in AoE2 DE (Steam version)

AoE2 DE Patcher - WIP

Patches AoE2 DE to any officially released version (Steam version only!)

Currently only suited for downgrading. To upgrade, please use steam to get to the latest version and downgrade from there if necessary. If i find the time and it's requested by anyone i might add upgrading as supported function back in.

Requirements

• Requires a steam account that owns the game
• Requires .Net Core to run (Console version is enough)

Usage

• Start aoe2de_patcher.exe
• Select desired game version & language (Language setting only affects cutscenes / campaign voice overs)
• Select the game directory
• Enter your steam login credentials
• Click <Patch>
• If prompted, enter the 2FA code
• To restore the previous game version hit <Restore> after patching (Make sure the game is not open in steam anymore since it will show an error then)

This whole process might take a while to finish, please wait until it says - DONE!.

Notes

Your login creedentials will not be stored.

For now, try to avoid closing the program via task manager while it is downloading. Currently I have not found a way to guarantee that downloads will be stopped after doing so!

FAQ

Q: Where is the aoe2_updater.exe file?
A: Please check that you downloaded the compiled zip file from the Releases tab and not the source code.

Q: The patcher says "Could not patch" and "DOTNET core not found". What is wrong?
A: You need to install DOTNET core to use the patcher. Please check the reuqirements section above for a link.

Q: What is the 2FA Code?
A: It's the code from your steam authenticator app if you have it enabled. Otherwise check your emails for a code.

Q: Where is the AoE directory?
A: Most likely it is this by default: C:\Program Files (x86)\Steam\steamapps\common\AoE2DE - It could be different for you though.

Q: Do I have to download a new version of the tool when a patch for AoE releases?
A: Usually not. If there is a new version available you will be informed when you start the tool.
