I just upgraded (clean install) to Vista Business, and the original CD I received with the LF PK1 will NOT install. I was told today that I need to PURCHASE the LFPK20 (or something like it) in order to use the device in Vista. Anyone else have this problem? Basically, the installer loads and I input the key, and nothing happens when I press Next. After pressing Next four or five times, it goes to FINISH and says the installation was interrupted. Anyone ? Thanks.

I know this thread is crazy old. But did you ever get resolution for your problem? Im having the same issue.

If you have not resolved the issue yet. Go to sony site they have free download of the software.
