"Something" on the machine appears to be conflicting with Virtual CloneDrive. So you might want to get rid of Virtual CloneDrive for the moment.
The easiest method is this:
After reboot, when asked if you want to install the driver, answer "no".
Now install Virtual CloneDrive again. When asked if you want to install the driver, answer "no". As the setup finishes, you'll get an uninstall option in "add / remove software". Now you can uninstall Virtual CloneDrive completely.
