SoftwareUpdateFiles.dll can not be found...

Hello everybody,

First I want to say sorry if my English isn't good, but I need help...

I'm working on a Windows Vista Business PC and I have a problem with Apple's SoftwareUpdate. Ervery time I start the program I get this error:

(Ok, it's in Dutch sorry!) But it's an error dat the part SoftwareUpdateFiles.dll isn't found. I already downloaded the part from internet and replaced it in the map, but that didn't work... I'ts very strange because a minute before the error i updated Quicktime... I hope it's clearly.

Thanks,

Thomas van der Wolde
