PostgreSQL 9 install on Windows: "Unable to write inside TEMP environment path."

Question

Some googling around yielded some advice that suggested Windows Scripting Host might be disabled. I've checked and WSH is definitely enabled, so it must be something else. Question is, what?

Any help appreciated.
