64-bit OpenROAD uses setup.exe or ormsiexec11.bat to install 64-bit OpenROAD 11.1 on Windows machines. 64-bit OpenROAD can be installed into an existing 64-bit Actian X instance or a Standalone Net Client (S/A Net) can be configured by the installer. If the 64-bit Ingres 11.1 is configured as a DBMS instance, an Actian Ingres 11.1 license must be configured. If the 64-bit Ingres 11.1 is configured as a S/A Net Client instance, then an Actian license is required if installing OpenROAD Development or OpenROAD Server. OpenROAD 11.1 cannot be installed into an existing Actian X Client Runtime.
