Cristie product components may show invalid digital signatures on Windows 2008

After installation on Windows 2008 SP2 Cristie product components (i.e. DLL and EXE files) from version 8.1 or later may show invalid digital certificates. For example:

This is caused by the SHA-256 based certificate that Cristie now uses in its product components. Windows 2008 SP2 (both 32 and 64 bit) does not fully support certificates of this type - see here.

Note: this does not affect the normal operation of the installed Cristie product.
