RBS configuration for more than 2 database

Hi, 

I've some trouble to configure RBS for more than 2 database, 

I'm using Sharepoint 2010 and SQL 2008 R2

my environement is : 

2 WFE

2 APP

1 SQL

I have already configure RBS for 2 of my database (via technet article)

I have my file in the Folder and all is great but when i want to configure my third database when i execute the rbs.msi manually, i just have the choise of " repair, remove or modify". 

When i execute the following command (as an admin) : 

msiexec /qn /lvx* rbs_install_log.txt /i rbs.msi REMOTEBLOBENABLE=1 FILESTREAMPROVIDERENABLE=1 DBNAME="PORTAIL_PROFORM" FILESTREAMSTORENAME=FilestreamProvider_1 ADDLOCAL=EnableRBS,FilestreamRunScript DBINSTANCE="srv2k8r2sql1.proform.dom\SHAREPOINT"

I have the line "configuration succesfull" in my log file but no table in sql :/

thx for all help
