Oracle 12c Installation failed to access the temporary location

Question

I have Windows 8.1 64-bit OS running on 64-bit architecture. I am installing a fresh copy of Oracle 12C, means I haven\'t installed any version before on my system.

Answer 1

I found another situation in which this problem may arise (despite following the steps listed by other users above) and that's when the username of the user you're logged in as has an '_' on it. The path it will try to use to find the temp directory is whatever is set in %TEMP%. I managed to work around it by:

1. Launch cmd.exe in Administrator mode
2. SET TEMP = C:\TEMP
3. Run the installer from that command window

Installed successfully that way.

Answer 2

Install it from CMD using the command

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