M-Files executables use only SHA-2 code-signing
Posted by Sakari Heinonen (M-Files) on 12 June 2019 11:23 AM

In the past, M-Files executables have been dual-signed with both SHA-1 and SHA-2 code-signing algorithms for better backward compatibility. Due to weaknesses in SHA-1 algorithm and to align to industry standards, executables of M-Files Online June '19 Update and M-Files 2018 Update 1906 and later are going to be signed only with the more secure SHA-2 algorithm. While this should not cause any issues, according to Microsoft, some Windows 2008 R2 and Windows 7 computers that do not have the latest Windows updates installed may be affected.

If you encounter any issues on Windows 2008 R2 or Windows 7 computers when updating M-Files, please make sure that you have the latest Windows updates installed. If installing the latest Windows updates does not resolve the issue, do not hesitate to contact us at support@m-files.com.
