Qt Visual Studio Integration 1.4 – error

Hi,
I have Windows Vista x64 SP1 (OS)
Acer Aspire 4520
AMD Turion 64 2.2 GHz
2 GB DDR2
I have run Visual Studio 2005 SP1 for Window Vista, Microsoft .NET framework 3.5
I fruitfully installed Qt 4.4.0 however when I attempt to install Qt Visual Studio Integration 1.4 I receive the error message:

Service Pack 1 for .NET Framework 2.0 is not installed.
Qt Visual Studio Integration for VS 2005 will not work properly without it.
You will not be able to choose the QT Visual Studio Integration for VS 2005 component for installation.
However I have installed Microsoft .NET Framework 3.5 that should be sufficient.
Pointed on the internet regarding this problem, I found:

Somebody can offer me a hand on this?
Thanks.
