[INS-30131] Initial setup required for execution of installer validation failed.

When trying to install Oracle client 12c the above error appeared , this issue can happened on windows Or linux.

The cause i really simple :-

On linux there is no enough space under /tmp.

On windows the solution like the following :-

  • Open Windows Services.
  • Stop Oracle Services –> OracleRemExec
  • Remove the OracleRemExecService
  • then try to install Oracle client again

Thank you
