D5Render installation verification failed with session name "Benoît"

D5 Render Version: 3.0.1.0683
Graphics Card: RTX3070Ti
Driver Version: 591.86
Issue Description:
I just updated my version of D5Render and got an error at the end of the installation (see log).
The problem is with the Windows user account name, because my account is “Benoît” and it installed everything under “Beno顃”.
I then uninstalled and reinstalled everything, but the result is the same.

Hi @benoit

I apologize for the inconvenience. This is a known issue with Unicode character handling in Windows user paths. D5 cannot properly resolve paths with non-ASCII characters (like “é” in “Benoît”).

What we recommed for now:

  1. Create a new Windows account with an ASCII-only name (e.g., Benoit) or you can rename it.
  2. Reinstall D5 under the new account
  3. Move your projects to the new location
  4. Alternatively, if you install D5 to a non-user path (e.g., D:\D5Render), it may bypass the issue entirely.

We’re aware this is a limitation and are working on a fix for future versions
