I suggest you try a different desktop machine. That worked for me when I had a similar issue installing 4.5
Other option is to do a clean desktop manager iremove and nstall. That includes registry clean up. If you are interested (and comforable poking about the reg) here is the info:
Perform a clean uninstall of BlackBerry Desktop Software
