An extension to the suggestions provided in https://plutonium.pw/docs/update/

• Plutonium.Updater.Core.Models.UpdateException: Failed to update file bin/VibeCheck.exe ---> System.UnauthorizedAccessException: Access to the path 'C:\Users\USERNAME\AppData\Local\Plutonium\bin\VibeCheck.exe' is denied.

Exclude/whitelist the Plutonium folder from antivirus scanning and remove anything related to it from the AV program's blacklist.

• System.ComponentModel.Win32Exception (0x80004005): An Application Control policy has blocked this file

Disable Windows Smart App Control.

• System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: The handshake failed due to an unexpected packet format.

Something is interfering with your connection to the CDN. Malwarebytes antivirus' web protection tends to do that. Add the websites plutoniummod.com and plutonium.pw to the allow list of the antivirus (Malwarebytes), remove them from the blacklist, and allow them through any other thing that is blocking them.

• System.Threading.Tasks.TaskCanceledException: A task was canceled.

• System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond [IP]:443

• System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it [IP]:443

• System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.

• Plutonium.Updater.Core.Models.UpdateException: Failed to update file storage/iw5/mp_nuked.iwd ---> System.Net.WebException: An exception occurred during a WebClient request. ---> System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception: The specified data could not be decrypted

Try these suggestions:

• Press Shift + right-click in the folder plutonium.exe is in, select "Open Powershell window here", then write and execute this:

  .\plutonium.exe -timeout 0
  

• Cloudflare DNS/Google DNS

• Cloudflare WARP/Proton VPN

If it doesn’t work after that, restart your PC, have the VPN connected, and relaunch plutonium.exe (the installer/updater) every time it fails.
