Unable to use Demucs-GUI versions beyond 1.1a2

[EtemT]

Hello! I have a strange issue where GUI versions released after 1.1a2 do not seem to open on my machine. 1.1a2 works just fine, but for all versions after, when I try running the Demucs-GUI.exe file, I'll get the command prompt window appear for a second, then disappear, but the program itself not open. I've tried the following troubleshooting steps:

• Running DemucsGUI as administrator
• Clearing the AppData\Roaming\demucs-gui folder
• Downloading the latest versions of Python and PyTorch (from what I can see this shouldn't make a difference but thought I'd give it a go.)
• Tested both the CPU and CUDA versions, both not working (1.1a2 CUDA is what I'm using at the moment).
• Moving the installation directory to the same place I have 1.1a2_cuda.
• Doing all of the above after restarting my computer

Below is the log file, which lists that a File couldn't be found, but I'm not sure what file I'm missing or what it's failing to load exactly. Am I missing something obvious or silly? Apologies if this is not the right place for it!

It seems that your system doesn't have wmic.exe

[CarlGao4]

Please press Win + X, and select PowerShell (Adminstrator), and paste the following command into the terminal window:

[Environment]::SetEnvironmentVariable("Path", [Environment]::GetEnvironmentVariable("Path", "Machine") + ";C:\Windows\System32\Wbem", "Machine")

Then press Return, and restart your computer
