Resolution:

1. Open registry editor as administrator
2. Goto Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MBAM Server\Enabled
3. Right click Reports and choose Modify
4. Modify the value from 1 to 0
5. And re-run the MBAM setup to add Reports configuration again.

Let me know in comments if you have alternate way to resolve the error.
