In our environment we are blocked by GPO from running any executable program in a folder other than C:\Program Files, C:\Program Files (X86), or C:\Windows. Oracle doesn't allow a space character to be in the ORACLE_HOME directory, so we can't use C:\Program Files\Oracle or C:\Program Files (X86)\Oracle. We've tried using C:\Windows\Oracle as the ORACLE_HOME, and the installation completed successfully. Administrators can execute SQL*Plus, SQL Developer, etc., but regular non-admin users can't access those.
Is there some way we can install Oracle 12c in a C:\Programs Files\Oracle on Windows 7 and/or Windows 10? That would allow regular users to run SQL*Plus and SQL Developer on the systems.
