Qt installation problem

[uniunit]

This is what I downloaded
Qt libraries 4.8.6 for Windows (MinGW 4.8.2, 328 MB) (Info)
The message is extract: error writing to file src\gui\painting\qdrawhelper.cpp
where can I find libraries with full package?

Hi and welcome to devnet,

Did you check that you have enough space to do the installation ?

Now it is installed. checked disk space. But installer isn't made properly, because it said firstly that space is available
