Question - supported export public key certificate (SED 10 or higher) in format X.509 (*.cer)?

http://www.symantec.com/connect/forums/export-public-key-certificate Don't work with SED 10.3.2 MP6 (File "pgp.exe" not found so commands said the link is not supported)

Ok. Download and trying to install "PGP CommandLine 10.3.2 MP3". Fail...

Error = An incompatible version of the PGP SDK exists on this system. Please uninstall any PGP products and try again. Installation terminated.
