NSIS Error: Can't create temp folder/Access is Denied

This happens on my laptop.It came with a preinstalled Vista Home Premium, and whenever i try to install something, i get this error:



And i can't do anything.Basically it happens on every program i download, i found a temporary way to put the files on USB so i can install them, but it's not a solution.

This error has been discussed before, I suggest you try searching the forums.

I tried the FAQ.I tried everything.Tried even system restore, nothing.

Nevermind, it seems Chromium was corrupting the files i downloaded from it somehow, and it corrupted the folder too.Sorry for your trouble.
