FSM 6u20 on premise installation error - Metadata import error occurred

Hi Experts: 

I attempted to install FSM (On Premise), each time it fails with the following error (Admin user sa is used). Any Idea?

Starting install, parameters passed:
Server name........FSMINS
Admin user.........sa
Admin password ....**********
Database...........fsmdbprod
Database user......fsmdbprod
Database password..**********
Backup Folder......C:\mxserv 6u20\DatabaseData\SQLServer\NewInstall
Installation parameter check passed.
Testing database connection...

Database    : master
ElapsedTime : 0.0189728
Server      : FSMINS
User        : SQL (sa)
Connection  : Successful

...verifying sqlcmd utility...
......searching folder = C:\Program Files...
......searching folder = C:\Program Files (x86)...
Everything seems to be order, continuing new install!
Importing metadata database...
......started at 22:33:25...
Metadata import error occurred!  Check sqlError.txt for details.
Cannot continue.

Error in the txt:
*** Unrecognized command line argument 'Instalation\FSM'.
