Anonymous 2015-01-06T09:57:08+00:00 Hi, Could anyone at this splendid froum take some of his precious time to really answer my questions: First:: I have a windows 7 Home Premium 64Bit, and there are three shourtcuts of the programs Microsoft Office 2010, Microsoft Offic Click-to-Run 2010, and Microsoft Office Starter 2010, which came pre-installed from the HP factory with my HP laptop. When I want to upgrade to Windows 7 by running Upgrade assistant, I found those three applications are listed which are Microsoft Office 2010, Microsoft Offic Click-to-Run 2010, and Microsoft Office Starter 2010 However, I really know how to run Microsoft Office Starter 2010 , and the two others (Microsoft Office 2010, Microsoft Offic Click-to-Run 2010, and Microsoft Office Starter 2010) I don't know them. So, my question is what those (Microsoft Office 2010, Microsoft Offic Click-to-Run 2010, and Microsoft Office Starter 2010). How to use them to benefit from them. **Second:**if the Q drive is a virtual drive which is used with Click to Run Versions of Office, such as some Office 2010 installations and all Office 2010 Starter installations, then how to use it. I am expecting Q drive would have been mounted with the document file being opened. However, I didn't see that there was anything on that virtual drive indicating that there was a file opening inside the virtual drive. As you might see my screen shot above, the virtual drive named by 'Q' was not being mounted by any files, althought there a file was being opened by choosing 'Microsoft Office client virtulazation handler' 0 comments No comments Could anyone at this splendid froum take some of his precious time to really answer my questions: First:: I have a windows 7 Home Premium 64Bit, and there are three shourtcuts of the programs Microsoft Office 2010, Microsoft Offic Click-to-Run 2010, and Microsoft Office Starter 2010, which came pre-installed from the HP factory with my HP laptop.
