Where can i get this execution file? What installer should i run?
ipisql.exe is installed as part of the core PI Server setup, and lives under your %PISERVER% install path. There is no separate installer for it. What do you want to do with this utility?
John is correct that the executable is installed as part of the PI Server installation. With that being said, it refers to the now deprecated PI SQL Subsystem. What is your intention for using it? The only two things that use it are the PI ODBC Client (which has been replaced by the OLEDB based PI ODBC Driver) and the GetPointsSQL PISDK call (which is used in the Advanced tab within the tag search menu).
