Sorry Sharmas I was sure to have written it right and double checked it too....
I want to say 6.4 not 4 (I thinked 6.4 and wrote 4 instead).
So the configuration is SnapDrive 6.4 (windows), VSC 4, Snap Manager for SQL 5.2 .
When installing SnapDrive 6.4 I got the connect to vcenter and it goes on correctly then I got the Connect to SMVI but it was not connecting through the default port (8043).
I've just checked and the problem was that SMVI service was stopped. I restarted it and reconfigured snapdrive and now the installation completed successfully.
Tomorrow I'll try some backup.
