I have postgresql9.3.exe one my computer. when I try to initiate the by running the following command:

postgresql-9.2.4-1-windows-x64.exe --serviceaccount postgres --servicepassword abcd1 --servicename PostgreSQL --prefix C:\abcd\PostgreSQL\ --datadir C:\database\postgresql\ --mode unattended

It is supposed to extract all the binary files to folder "C:\abcd\PostgreSQL\" however it is creating a new folder "C:\abcd1\PostgreSQL\" and extracting all the binaries there.

I am not sure why it is not getting extracted at another location than specified.

Need help
