Cannot Remove Microsoft Office 2010 Click To Run

I recently got a laptop with a Starter version of Microsoft Office 2010 installed on it. As this Starter version does not give full use of the features within Excel, I wanted to install my Home and Student Office 2007. I installed Office 2007 alongside the Starter 2010, however this caused quite a few problems with File associations so I decided to uninstall Office 2010, unfortunately this meant that Office 2007 also did not work as I believe I hadn't installed and uninstalled things in the right order. I therefore did a system restore to when Office Starter 2010 was on the laptop without 2007. I uninstalled both the Office Starter 2010 file and the Office 2010 file from the Program files. I tried to also uninstall the Office 2010 Click to Run file, however this would not uninstall. It just comes up with an error message "this action cannot be completed. try action again. if problem continues, contact microsoft product support". I have now installed Home and Student Office 2007 and it seems to be working, despite the Office 2010 Click to Run file still being on the computer. Is it okay to leave the Click to Run file and the associated Q drive there and be running Office 2007? Or do I need to make sure I eradicate the Click to Run altogether?
