Can't update Copilot Plugin in Rider: access denied exception on copilot-language-server.exe

Body

Most of the time when I update the Copilot plugin inside Rider, I get this error message:

The IDE failed to install or update some plugins.
Please try again, and if the problem persists, report it to the support.

The cause: java.nio.file.AccessDeniedException: C:\Users\ursen\AppData\Roaming\JetBrains\Rider2024.2\plugins\github-copilot-intellij\copilot-agent\native\win32-x64\copilot-language-server.exe

Updating the plugin without an open solution (from the load screen) works so far.

I have the same issue with PHPStorm.

I'm having the same issue across multiple installations. However, I just can't install the updates at all; with a project open or from the welcome screen.

I advise to follow 4 steps.

1. Close all open solutions
2. Run Rider as an administrator
3. Manually delete the problematic file
4. Check file permissions

If you need some more details, feel free to contact me directly.
Hoping this answer will be of some help to you.

Can you explain it in more details?
You gave us the common method that we all know.

I am sorry for not detailed description. I update it for all of you.

1. Close all open solutions before updating the plugin
   As creator mentioned, updating from the load screen works, so continue doing that.

2. Run Rider as an administrator
   Right-click the Rider icon and select "Run as administrator" to ensure it as the necessary permissions to update plugins

3. Manually delete the problematic file
   Navigate to the specified path and delete copilot-language-server.exe, then try updating the plugin again

4. Check file permissions
   Ensure the plugin folder and files are not write-protected by reviewing their properties and adjusting permissions if needed.

Thank you for your answer.
I will check this and send the result.

The above instruction resolved the issue for me. However,

• You should delete copilot-language-server.exe before running Rider as an administrator, otherwise the file is locked.
• Also 'specified path' is %appdata%\JetBrains\Rider2024.2\plugins\github-copilot-intellij\copilot-agent\native\win32-x64\

It worked for me as well the steps I performed after some didnt work:

1. delete the problematic file (copilot-language-server.exe)
2. tried updating again and it was fixed.

no need for admin rights or anything like that. After updating the file gets reinstalled in the same place
