All of the following criteria must be met

• All Requirements must be installed.
• Changed the title so that it doesn't just says "[Bug]: "
• I have searched the GitHub issues for my bug, even in the closed issues.

All of the following are optional to answer

• Tried reinstalling the Game.
• Tried reinstalling MelonLoader.
• Tried restarting PC.
• Was able to see the Start Screen.

Describe the issue.

If previously using MelonLoader on an executable (Schedule 1, in my example), and then manually downloading using steamcmd the Mono version of Schedule 1 to a completely different path (for both IL2cpp and Mono development simultaneously) the MelonLoader installer will report that the game is already listed, and not install to the second Mono location.

In this case, you cannot have two copies of the same game in different directories installed, which means I need to reinstall the same via steam to the same path, which is a minor time delay but still technically a development hindrance so I thought I'd report it.

Thanks!

Did you attach your log file?

No, I could not find a log file at {Game_Directory}\MelonLoader\Latest.log

My fault, this should have been in https://github.com/LavaGang/MelonLoader.Installer/issues

Opened under the installer here: LavaGang/MelonLoader.Installer#49
