error while installing SMD agent

Hi ,

1) Can any one please justify/brief the need of installing SMD agent on ABAP stack?

2) When I tried to install the SMD  711 agent on ABAP stack I could see the below error when i click sapinst.exe.

    " Running msiexec failed with return code 1063: undefined

      command line was :

       msiexec.exe /norestart /L vcredist_x64.log /i vcredist_x64.msi /qn "

I tried with Changing the environment variable of Temp and tmp to C:\usr\sap\<sid>\tmp  and also tried with directory c:\temp but in vain .

enivronment:-   Windows 64-bit.

Note:- SMD agent was successfully installed on Development systemn

Please suggest.

Thank you

Jayanth
