I used WPS 6, just make sure to monitor non-microsoft odbc links. Also need to add write permissions to the install dir - easy to do if software is deployed through Group Policy.

For version P6 8.2 the following command line can be used in a Windows 7 environment. This is for a configuration where the DB is in production environment. A 2nd script is used to copy an .xml file per profile with the DB connection information:

Main install:

rem Installing prereqs which is only DHtmlEd since .net 4 is already in environment, and a production sql database is being used so java and oraclexe is not needed
msiexec /i "%~dp0DHtmlEd\DHtmlEd.msi" /quiet /norestart
rem Installing main install - Note: separate script in user context applies config file necessary to setup database connection
msiexec /i "%~dp0P6Professional-setup.msi" /quiet /norestart

Per profile script:

rem Create directory for copying config file in next step
md "%UserProfile%\AppData\Local\Oracle\Primavera P6\P6 Professional"
rem Copy config file per Profile
copy /Y "%~dp0DB config\PrmBootStrap.xml" "%UserProfile%\AppData\Local\Oracle\Primavera P6\P6 Professional\PrmBootStrap.xml"
