How can install service from a server to the same server ?
Only remote installation is available ?
You can use the ServerInstaller.exe program within the Program Files directory (usually within C:\Program Files\One Identity).
Note that it may not be called "One Identity" in versions before V8 (maybe Dell...)
Also, this directory will only be visible once the admin tools are installed on the machine which can be done by running the autorun.exe program from the OneIM Installation files.
