LogonCommand doesn't execute in windows sandbox

I was trying to use Windows Sandbox to run UniFi server and I wanted to install VC140 as a logon command which seemed to not work 🤔 I was mounting the Desktop folder where I had both the executable and the startup.cmd file. Opening the sandbox and running the script worked. This means that the LogonCommand should also work, right? 

VC_redist.x64.exe /install /quiet /norestart

Well, no, because the scripts needs to use full paths as mentioned in this youtube video.

Running Ubiquiti UniFi Network Server on Windows 11

I was trying to run the self-hosted UniFi Network Server v8.0.26 on a newly installed Windows 11 but I was getting a cryptic message "Server taking too long to start…" followed by a "Start-up failed" error. It turns out that VC140 runtime is a hidden requirement (Visual C++ redistributable aka MSVC) and in my case it worked fine installing the latest MSVC for 2015,2017 and 2022 available in the official Microsoft site. Here is how I discovered the missing dependency.
