Issue/Introduction:
Windows 7 and Windows 8 support UEFI (Unified Extensible Firmware Interface) implementations.
Symantec Encryption Desktop version 10.3.1 (formerly known as PGP Desktop) introduced support for systems running Microsoft Windows 8 64-bit in UEFI mode. Versions previous to 10.3.1 of Symantec Encryption Desktop do not support this configuration.
Resolution:
- Symantec Drive Encryption 10.3.0 and previous did not support computers using UEFI firmware.
- Symantec Drive Encryption 10.3.1 includes UEFI support for Windows 8, but not Windows 7.
- Symantec Encryption Desktop 10.3.2 has support for UEFI for Windows 7 64-bit and Windows 8.0/8.1.
- Symantec Drive Encryption 10.3.2 and above now supports GUID Partition Table (GPT) formatting on Microsoft Windows 7 64-bit systems and Windows 8.0/8.1 64-bit systems, running in UEFI mode. Systems using UEFI should upgrade to Symantec Drive Encryption 10.3.2 or above to obtain this full support for this new functionality.
