Compatibility Report

  • Name of the game with compatibility issues: Halo Reach Mod Tools - MCC
  • Steam AppID of the game: 1695793

System Information

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

The game can install dotnet35 and 45 through Soda, using Bottles on my system. However, this gives an unhandled exception: https://gist.github.com/orowith2os/f552749c2ccc8814bfdc5dec4fa21983
Normal Proton does not work, even with the protonfixes system. .NET does not install with Proton, for some unknown reason.

Reproduction

(for Bottles)

  1. Install Bottles from Flathub
  2. Install the Soda runner
  3. Make a new bottle with the Soda runner, install dotnet35 and dotnet45
  4. run Foundation.exe from the Halo Reach Mod Tools

(For Proton)
Need to try some more, will list here when I have logs and the like.

The other mod tools do work with a few fixes, which I've added to @GloriousEggroll's protonfixes fork

Proton Log doesn't generate when I launch the tools

Symptoms

All the tools from the editing kit (Tagtest, Sapien and MegaloEdit) launch correctly except Foundation. When you try to launch it, Steam says that .NET Framework 3.5 and 4.5 are needed.

I tried installing those packages using Protontricks, but Foundation still refuses to open. The only progress I got is making the warning message disappear

Reproduction

Just start game and select "Launch Foundation"

I've been experimenting with Foundation more during these days.
I tried running it from my dual boot W10 installation on Gnome Boxes, but it doesn't launch there even after installing .NET 3.5 and 4.5 (obviously the other tools work).
However, if I install the modding tools from Steam on the W10 Gnome Box, Foundation works fine.
My theory is that there are some other depencies we still don't know, which are installed by Steam but are not included in Proton

I got Foundation working on my system's wine-staging 11. The program says it needs dotnet 3.5 and 4.5, but this seems to be wrong as dotnet35 + dotnet45 caused it to crash. I tried winetricks dotnet35sp1 and dotnet48 instead, and then it works fine.
