The Simplify Suite install is in windows installer format, allowing
for silent installations and deployment through Active Directory. Silent
install is initialized using the /q switch with msiexec.exe, and then
passing in values for properties. The command line syntax to set a property
is PROPERTY=VALUE. Valid properties include:

INSTALLDIR
SQLSERVERNAME
SQLTRUSTED
SQLUSERNAME
SQLPASSWORD

Below is an example of correct syntax to begin a silent installation
of Simplify Suite.

msiexec /i simplify.msi /q SQLSERVERNAME=SQLSVR SQLTRUSTED=no SQLUSERNAME=sa
SQLPASSWORD=sapwd

SQLUSERNAME and SQLPASSWORD are only necessary when SQLTRUSTED=no. If
SQLTRUSTED=yes, then the install ignores the SQL username and password.

A silent installation cannot be performed using the install bundled
with the MSDE (SimplifyMSDE.exe). Instead, the (Simplify.msi) will is
required. Additionally, a silent install cannot perform database operations
such as creating a new database. A simplify database must already exist
for the silent install to work.
