Bug Report
I wanted to update my agentic toolkit to the latest release, but got the following error-message:
setupAgenticToolkit("install")

Error using setup.downloadMCPBinary
Download failed:
Unable to open output file: 'C:\Users\xxx.matlab\agentic-toolkits\bin\matlab-mcp-core-server.exe' for writing. Common reasons include that the file exists and does not have write
permission or the folder does not have write permissions.
Try downloading manually from:

Error in setupAgenticToolkit
Error in setupAgenticToolkit
Analysis and fix by github copilot:
The issue was not missing write permissions. The existing matlab-mcp-core-server.exe was already in use by one or more running MCP server processes, so the installer could not overwrite it.
Use this procedure on Windows:
Close any tools that may be using the MATLAB MCP server.
This usually means VS Code, Copilot sessions, or any other agent host connected to MATLAB.
Open PowerShell.
Check whether the MCP server is still running: Get-Process matlab-mcp-core-server | Select-Object Id,ProcessName,Path
Stop the running MCP server processes: Stop-Process -Name matlab-mcp-core-server -Force
Run the MATLAB installer again: setupAgenticToolkit("install")
Why this works:
The target folder was writable.
The installer error message was misleading.
The actual problem was that matlab-mcp-core-server.exe was locked by a running process.
I would expect the installer to handle this and to receive a prompt before any running processes are being closed
Additional Context
No response
