Copy Protection on the Petroleum Engineering Handbook CD-ROMs

The Petroleum Engineering Handbook (PEH) CD utilizes the HexaLock CD copy protection system. This system requires the user to have administrator privileges on the computer PEH is running on. Affected systems and solutions are described below. Please provide this information to your company’s IT department if you are unable to run the PEH CD.

PEH software is PC compatible only. Affected operating systems (OS):

  • Microsoft Windows 2000
  • Microsoft Windows XP
  • Microsoft Windows Vista

Description of the HexaLock procedure

The HexaLock CD copy protection system requires direct access to CD-ROM drives in order to authenticate copy protected discs. Windows 2000, Windows XP and Windows Vista operating systems prevent applications from accessing storage devices directly if a user who does not have local administrator privileges attempts to run them. This limitation prevents HexaLock protected CDs from completing the disc authentication procedure. In that case, the program execution is stopped, and the following message is displayed: “You must be a local administrator to run this program.”


There are two ways to run the PEH CD. The first is to grant local administrator privileges to the user who tried to run the CD. The second is designed for cases where permanently granting local administrator privileges is not desired. For these cases, HexaLock has developed a utility that enables protected CDs to run without requiring local administrator privileges. This utility needs to be run only once with local administrator privileges enabled. To run the utility, follow these instructions:

  1. On the Internet, log on to http://www.hexalock.com/downloads/RemoveRights.zip to download the Remove Rights Utility.
  2. Login to your Windows OS using an account with local administrator privileges.
  3. The utility is compressed in a .zip archive. Extract the .zip file and run the Remove Rights Utility on the affected computer. The utility will display a black window for a few seconds and then terminate.
  4. Restart the computer. You can now run HexaLock protected programs without local administrator privileges on this computer.
