Uninstalled all previous version of vectoworks, and reinstalled v 9.0.1. Trying to update to version 9.5 I still get the same error message.

I get the following error trying to update to 9.5: The updater could not verify your installed copy. Please go back and select a new location, quit and reinstall your Version 9.0.1 product, or enter a different serial number. I have tried to reinstall, but it still doesnt work. Installing 9.01 goes just fine. Any ideas ?
