Dynare 6.3 preprocessor blocked by Windows 11 Smart App Control (MATLAB R2024b)

Installation and Setup

Hello Dynare Team,

I use Dynare 6.3 with MATLAB R2024b for academic DSGE research on Windows 11. It worked in earlier runs, but Windows Smart App Control is now blocking E:\dynare\6.3\preprocessor\dynare-preprocessor.exe before preprocessing begins. Windows Code Integrity Event ID 3077 reports the VerifiedAndReputableDesktop policy, with related events 3033 and 3089. Get-AuthenticodeSignature reports NotSigned.

SHA-256 (local dynare-preprocessor.exe): 0BB3EECED5BBD58B45C05AFAD0D72B8AA890422DCABBC776D06C3A4DB29C6DF4

Could you please confirm whether this hash corresponds to an official Dynare 6.3 Windows preprocessor? Is an officially signed package available, or a supported way to run Dynare 6.3 while retaining Smart App Control? Is the Dynare 6.3 package for MATLAB Online an option for reproducing saved results as an alternative? Preserving the same Dynare version is important for reproducibility. I would prefer not to disable Windows protections.

Thank you for your guidance.

Sorry for the delay. The hash is indeed correct. MATLAB Online does not help, because it does not preserve the MATLAB version and therefore is not reproducible. Unfortunately, we have no way of influencing Microsoft’s Smart Screen. You seem to need a userbase in the millions to reliably not get flagged as a potential threat.
