If you're application connects to the internet for score updates then ...
Then you must have a website where you should have a web service that will fetch you updated details to your application...

If you look in Control Panel > Programs > Programs and Features > Installed Updates on a 3.5 SP1 Vista system, there are two updates that should always be there: "Update for Microsoft Windows (KB948609)" (2.0 SP2) and "Update for Microsoft Windows (KB948610)" (3.0 SP2). When trying a reinstall, make sure these patches are uninstalled from the system before the reinstall. After the framework is installed, these patches should appear again under Installed Updates, the SP keys under "NET Framework Setup" should be correctly set, and the SxS problem should (I hope) be repaired. If anything goes wrong, do post the install logs.

Despite that if the problem persists then you should perhaps look for any hotfixes installed that may have patched PresentationCore? You may want to check this and clean any files left behind when re-installing 3.5 Sp1, as mismatched versions occasionally lead to un-modified files.
