The Integrator program creates a task named WUMT2 that you can find under Task Sheduler. Open the task and edit the Actions tab where you can put any argument you'll like under "Add arguments (optional)"
What do you mean? The video clearly shows that the integrator is not working. WUMT has always worked if you run it directly, but doing so kinda defeats the purpose of this IMO.
Can you open task scheduler and try to run the task WUMT2 from there? You should have this command line under the "Action" tab: Start a program "C:\wumt\wumt_x64.exe" -update If that doesn't work, try changing location of the wumt folder to Program Files: "C:\Program Files\WUMT\wumt_x64.exe" and run the installer again.
While trying to download the file from Google drive it is flagged as file containing virus. You can try it yourself from the first link in the first page of this thread.
