Initial setup required for the execution of installer validation failed.

One of my colleagues asked me to deploy the Oracle 12c client 32 bits on Windows 64 bits and I got the error from above right after the I chose the type of the installation.


As per above image, the cause of it is – ” Failed to access temporary location”

I tried almost everything what I could find on Google…..from TEMP not correctly exported, the name of the user used, hidden share…..everything was “like in the book”….but was still failing with the same error. However, I have found this command:

setup.exe -ignorePrereq -J"-Doracle.install.client.validate.clientSupportedOSCheck=false"

and a miracle will happen.

    1. I’m sorry to hear that…..however, this is a generic error and can can pop up due to a number of reasons …. you might have hit a different cause of it and I have no idea about your setup.


      1. I’m getting the same error. All solutions tried. This is the last one and I hope it’ll work. But I don’t know where to write this command after running setup. Please guide


      2. Well.. first u have to use Windows for this installation… then open a terminal (command prompt) and point the current location where the setup.exe is. Then … just copy and paste the command from above and execute it ….. I guess that should be all ….
