Nsight Compute UI (ncu-ui.exe on W11) crashes on startup due to special characters in User path

Developer Tools Nsight Compute

Hi NVIDIA team,

I am reporting a reproducible crash in Nsight Compute UI (ncu-ui.exe) on Windows 11 (24H2, OS Build 26100.1, fresh installation). The application fails to launch if the Windows User Profile path contains non-ASCII / special characters (e.g., C:\Users\Mickaël).

The application crashes with a generic C++ exception code caught by the Visual C++ Runtime. The faulting module is VCRUNTIME140_1.dll – not sure if this library is the actual culprit. I attach the .dmp file.

Creating a new local user account with standard ASCII characters (e.g., Andrew) resolves the crash immediately on the same machine. In case it helps, Nsight Systems 2026.1.1 works fine even for users with special characters.

Thanks in advance!

Hi, @aurelio.hurtado-de-mendoz

Thanks for reporting this issue to us.
We tried internally, can not reproduce the crash.
I will let dev help to check the dump file to see if any clue.
Anyway, I hope this won’t block you.
