Directory Structure for Windows

[okumedia]

What is the right way to add temp directory in windows?
I tried the usual C:\Users\Temp and I got "Invalid tmpdir: C:\Users\Temp" and I also tried /mnt/disk0/ I got "Failed to write to tmpdir directory: '/mnt/disk0/'

I got passed it by "C:\ only without a directory inside of it. The problem I am facing now is "out of memory".

What are the minimum requirements?
