Hi,
I haven´t found any previous report of your Dell laptop model having issues with PGP.
This is from 10.2 release notes :
System Requirements
PGP Desktop can be installed on systems running the following versions of Microsoft Windows operating systems:
Windows XP Professional 32-bit (Service Pack 2 or 3), Windows XP Professional 64-bit (Service Pack 2),
Windows XP Home Edition (Service Pack 2 or 3), Microsoft Windows XP Tablet PC Edition 2005 SP2, Windows
Vista (all 32- and 64-bit editions, including Service Pack 2), Windows 7 (all 32- and 64-bit editions, including
Service Pack 1), Windows Server 2003 (Service Pack 1 and 2).
The above operating systems are supported only when all of the latest hot fixes and security patches from Microsoft
have been applied.
Note: PGP Whole Disk Encryption (PGP WDE) is not compatible with other third-party software that could
bypass the PGP WDE protection on the Master Boot Record (MBR) and write to or modify the MBR. This
includes such off-line defragmentation tools that bypass the PGP WDE file system protection in the OS or
system restore tools that replace the MBR.
