[?]: WinCC 6.2 in other windows 2003 installations Problems.

[Moof]

Dear Friends:

recently i installed wincc 6.0sp4 in a windows 2003 server sp1, without any problems.

Now i´m trying to install wincc 6.2 in other windows 2003 server sp1, exactly as the other and when the installer reachs the installations of the SmartTools it freezes and after 15 minutes or more, a warning apears saying this:

Severe:

Error installing a component:

SmartTools

and nothing else... anyone can help me?.
wincc works like nothing but i can´t install smart Tools.
