RBS installation - forgot some parameters

Hello.

I've installed RBS in my Sharepoint 2010 sever and instead of running

msiexec /qn /lvx* rbs_install_log.txt /i RBS.msi TRUSTSERVERCERTIFICATE=true FILEGROUP=PRIMARY DBNAME="WSS_Content_RBS" DBINSTANCE="INTRA01"FILESTREAMFILEGROUP=RBSFilestreamProvider FILESTREAMSTORENAME=FilestreamProvider_1

I've run

msiexec /qn /lvx* rbs_install_log.txt /i RBS.msi TRUSTSERVERCERTIFICATE=true FILEGROUP=PRIMARY DBNAME="WSS_Content_RBS" DBINSTANCE="INTRA01"

without last 2 parameters.

I've tried to run the script again with all parameters in place but rbs_install_log.txt after second run is about 500 kb, what means that installation failed (it was more than 1 mb after first run).

$rbs.GetProviderNames() shows FILESTREAM_Blob_Store instead of  FilestreamProvider_1.

Could you please say if RBS must be reinstalled with all parameters and how it can be done?

Thanks in advance.
