Version
What version are you using?

  • Stable release (3.5.0)
  • WIP release (version here)

Build
What runtime version are you using?

  • .NET 9.0 running on Windows 11 Build 26100

Describe the issue
I receive the following error when trying to start a dump with Redumper or DiscImageCreator.

Remote version: 3.5.0
You have the newest version!
Starting dumping process... please wait!
Look for the separate command window for more details
Executing Redumper... please wait!
System.ComponentModel.Win32Exception (1223): An error occurred trying to start process 'Programs\Redumper\redumper.exe' with working directory 'D:\MPF'. The operation was canceled by the user.

--- End of stack trace from previous location ---
   at MPF.Frontend.DumpEnvironment.Run(Nullable`1 mediaType, IProgress`1 progress)
   at MPF.Frontend.ViewModels.MainViewModel.StartDumping()

To Reproduce
Steps to reproduce the behavior:

  1. Launch MPF
  2. Insert a disc to dump. Tested with NFS: Pro Street on PS2, but disc doesn't seem to matter.
  3. Note that disc scans and is correctly identified
  4. Click 'Start Dumping'

Expected behavior
Redumper or DiscImageCreator launches and dumping begins

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context

  • Validated that the .NET 9.0 runtime is installed
  • Tried with 3.4.2, and with the latest rolling build
  • Tried running as Administrator
  • Tried disabling Windows anti-virus
  • Tried enabling all security permissions for the folder
  • Tried a different folder/drive
  • Same result in all cases

Not a bug, it's Windows marking everything with a pulse as dangerous. You need to go to the Programs folder and uncheck "Unblock" from both DIC and Redumper's executables.

Unbelievable. I thought I had chased down every way Windows tries to impede you, and they go and create another one. Sorry for the bogus report!
