Error when trying to use themes

[leedolman]

I've just finished my first service pack 2 slipstreamed unattended. Everything's gone smoothly, apart from one thing - themes will not work, even the default Luna theme.

I receive the following error when I attempt to load a theme:

Error Loading Visual Styles:

The visual styles could not be loaded because the file failed to load.

I used the modified Uxtheme.dl_ but now I receive this error.

Do you need a different uxtheme.dl_ for service pack 2?

Thanks

OK, I just figured out I do need a different uxtheme and have now downloaded the correct version for the build of SP2 I'm using.

However,

how do I now replace the existing uxtheme in my system32 folder, as it's in use
