I was going to installed our old robot in my company and by mistake I did 'I" start in robotstudio,
now I am not able to configure ,not even boot up my robot IRC5 and I have back up of all files but my robot studio is RW 6 any back up of mine is RW 5.16, now its asking for license.
its seems media pool Robot studio 5.6 which I don't have , secondly when I use installation manager its asking for different version
kindly help me >
thanks in advance 
In the root directory of a good backup open the system.xml file and observe the 'used media' information. That will let you know what ABB media will need to be to present and in what location.
If you do not have the necessary media contact your local (country's) ABB office and request the installer files. Ensure the paths the installer uses match your system.xml options.
E.g.:
<Media path="C:\PROGRAM FILES (X86)\ABB INDUSTRIAL IT\ROBOTICS IT\MEDIAPOOL\ROBOTWARE_5.15.8017" name="RobotWare" version="5.15.8017.08"/>
Good luck!
? I-start must reset Rapid,
the sistem must boot.
Are you sure you made a I-start and not C-Start .
RobotStudio version doesn't matter,you must be able to create sistem.
but how SomeTeak said we need a BackUp AND THE RIGHT VERSION OF RobotWare 5.?
You should be able to generate a new system with the trial version. Could you paste the “system.xml” file to see what you need?
load most recent backup
