UIAutomationCore Fix

Since the problem is caused by wine's incomplete UIAutomationCore implementation, there are two ways to fix it

Option 1: Getting UIAutomationCore.dll from Windows (or an ISO)

You will need to get the UIAutomationCore.dll file from C:\Windows\System32\UIAutomationCore.dll.

• If you have dual boot or another computer with windows 10 or 11 available, then you can copy the file from there to the prefix's drive_c/Windows/System32
• If the options above are not available, then you can download a clean Win 10 ISO from Microsoft and use that:
  1. Download the ISO from: https://www.microsoft.com/en-us/software-download/windows10ISO
  2. Either use the attached UIAC.sh script to extract the file (requires p7zip) OR do the following:
  3. Mount the Win 10 ISO and go to the sources folder inside OR extract install.wim using p7zip: 7z e ISO_PATH sources/install.wim
  4. Either mount the install.wim file using wimlib and copy the file from Windows/System32/UIAutomationCore.dll OR extract the file using p7zip 7z e install.wim 1/Windows/System32/UIAutomationCore.dll

Where to put UIAutomationCore.dll

Depending on how you installed Streamer.Bot, the location of where you have to place the obtained file varies:

• Using Lutris: Go to Game options, go to the directory set in Wine Prefix, then go to drive_c/windows/system32.
• Using Bottles: Inside the SB bottle, click the Browse C:/ drive option, then go to windows/system32.
• Using the install script: ~/.local/lib/streamer.bot/pfx/drive_c/windows/system32

#!/bin/bash
# Saving the script directory
DIR=$(pwd)

# Changing to a temporal working directory
cd "$(mktemp -d)" || echo Error changing to a temporal directory, \
        will use the script directory instead.

# Verifing that we have a working environment

if ! command -v 7z &>/dev/null; then
    echo Install the needed package: p7zip
    echo Fedora: sudo dnf install p7zip
    echo Debian/Ubuntu: sudo apt-get install p7zip-full
    exit 1
fi

# Asking for the ISO file
echo Insert the path to the Windows ISO file:
read -r ISO_PATH
ISO_PATH=$(realpath "$ISO_PATH") # Solving path, just because
echo

echo Extracting install.wim...
# Getting the install.wim from the ISO
if ! 7z e "$ISO_PATH" sources/install.wim &>/dev/null; then
    echo An error ocurred extracting the Windows installation file.
    exit 1
fi
echo

echo Extracting UIAutomationCore.dll...
# Get the UIAutomationCore.dll from the .wim
if ! 7z e install.wim 1/Windows/System32/UIAutomationCore.dll &>/dev/null; then
    echo An error ocurred extracting UIAutomationCore.dll from the installation file.
    exit 1
fi
echo

# Move the file where the script is called from and clean the directory
mv UIAutomationCore.dll "$DIR/UIAutomationCore.dll"
rm install.wim

echo "Done! UIAutomationCore.dll was extracted and moved to $DIR/UIAutomationCore.dll"

Option 2: Update to wine-staging

Depending on how you installed Streamer.Bot, the way of changing the wine version used is different:

• Using Lutris, change the runner (in runner options) to either:
  • wine 11.14 staging
  • System (if it's 11.9 or newer)
• Using Bottles, change the runner to either:
  • kron4ek's 11.14 staging or newer (NOT tkg, Recomended)
  • Built-in wine 11 or newer
  • kron4ek's 11.14 staging tkg or newer
• Using the install Script:
  • Check that your wine version is 11.9 (staging) or newer (use wine --version), if it's not, then you'll have to update wine, use your distribution's way of doing that or follow winehq guide to add their repos.
