This is caused by a bad autoexec.nt file on your computer which is preventing InstallShield from running. You need to
reinstall your autoexec.nt file. Microsoft has instructions to fix the problem by re-installing your autoexec.nt file
from your operating system CD at http://support.microsoft.com/?kbid=324767
This has only appeared on certain Dell machines, including the M65 and D820. It is caused by the Embassy
Trust Suite by Wave systems, that is preloaded on these machines, and prevents any installations using
InstallShield version 5. You can install by clicking Start, then Run, and typing "command" (not "cmd"). When
the DOS Window appears, type X:\setup.exe (where X is the drive that has the MFGO CD-ROM),
and the installer should run correctly.
You can also fix this by uninstalling the Embassy Trust Suite as described at
