Error 0x%08X while checking digital signature of %s: %s

The Require digital signature option is set on one or more installation files, but the indicated file does not have a valid signature.

Background information

It is good practice to apply a digital signature to the .exe programs that you distribute (and optionally to other executable files such as DLLs and ActiveX controls). The Require digital signature option helps you to enforce this practice by checking the digital signature on each file that has this option set.


Make sure that the files marked with the Require digital signature option are signed before the preflight check is performed.
