At a first look the installation process was ending correctly but whenever I try to start the service or the stand alone server nothing happens. When I tried to start the server from the command line I got something was missing from the installation folder… the entire data subfolder was missing!
After trying without success many installation options I tried to digg into the problem and what I’ve found is very strange: I don’t have the permissions to create that folder!
The strange thing is I had the permission to create the parent installation folder, all the sibling folders containing binaries, extensions and clients… but not the data folder!
I got the short way: I created the data folder, added myself as a user having all rights on the folder then I runned bin\initdb.exe -D data et voilà… the database is ready and working.
