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.
