http://igordcard.blogspot.dk/2012/03/unable-to-write-inside-temp-environment.html
try following last solution which will 100% work: (in my case it worked for
Postgre 9.2)
Step 1: Winkey -> Run -> type " %windir%\inf\ " without quotes.
Step 2: Right click on wsh.inf and select install.
And all done. Now your installation will work and you can run any .vbs file
also.
